Here are 8 prompts that turn Claude into your personal Excel expert 👇🧵 1️⃣ UNDERSTAND ANY SPREADSHEET

Upload your Excel file and use:

PROMPT:

Analyze this spreadsheet and develop a comprehensive understanding of its structure, purpose, and contents. Identify the types of data included, key metrics being tracked, relationships between columns, reporting objectives, and the overall business context. Explain how the dataset is organized, assess its completeness and quality, and provide an overview of the most important information it contains. Present the output as a structured briefing that helps a new analyst quickly understand the dataset before performing deeper analysis.

William Zinsser taught writing at Yale, then wrote the book that has fixed more bad writing than every English class combined.

Here are 10 cuts from "On Writing Well" that instantly make your writing twice as strong.

1) Delete every word doing no work Zinsser's first rule is the one that exposes every writer immediately.

Read your last sentence. Find every word that would leave the meaning unchanged if you removed it.

Those words are not neutral. They are actively making your writing worse. They force the reader to work harder for the same information. They dilute the words doing the actual work.

His test was brutal and simple. If a word is not earning its place, it does not get one.

Most first drafts cut by half. Most writers discover their ideas are cleaner than their sentences suggested.

Her Amazon orders were 18% more expensive than her sisters for the exact same products.

They lived in the same city. Had Prime accounts on the same plan. Were buying the same brands. Often within hours of each other.

Yet every single time they compared receipts, her totals were higher.

A laundry detergent her sister bought for $14.99 cost her $17.49. A pair of headphones her sister got for $79 cost her $94. A printer ink cartridge her sister paid $32 for showed up in her cart at $39.

She thought maybe she was looking on the wrong day.

Then a friend who used to work in Amazon's pricing team explained the truth over dinner.

"Amazon doesn't have one price. They have millions of prices, one for every customer. The price you see is calibrated specifically for you, based on what Amazon has learned about your behavior. Your sister is paying less because Amazon has decided she'll only buy at lower prices. You've shown them you'll pay more."

She asked how that was even legal.
He smiled.

"It's not just legal. It's the entire business model. Most shoppers have no idea this is happening and Amazon would prefer to keep it that way."

Here's everything he explained over the next 30 minutes. 🧵 1/ The first thing she learned: Amazon adjusts prices up to 2.5 million times per day.

This isn't an exaggeration. It's a documented business operation.

Amazon's pricing algorithm changes the price of millions of products throughout the day based on:

— Demand patterns (how many people are looking at the product right now)
— Competitor prices (what Walmart, Target, and others are charging)
— Time of day (prices often rise during peak shopping hours)
— Inventory levels (low stock triggers price increases)
— Customer behavior signals (the part most people don't know about)

By comparison, Walmart adjusts prices roughly 50,000 times per day. Target does even fewer.

Amazon's price for the same product can shift as many as 20 times in a single day for the same SKU.

This isn't price gouging. It's "dynamic pricing." And it's been refined over 25 years into one of the most sophisticated profit-extraction systems ever built.

PAUL GRAHAM JUST SAID THE QUIET PART OUT LOUD!!

The man behind Airbnb, Stripe, Reddit, and Dropbox just dropped the simplest money formula on the internet.

Make something people actually want.

And with Claude, one person can now test that idea in a weekend.

Here is the full breakdown 👇🏽👇🏽 1. WHO IS PAUL GRAHAM AND WHY DOES THIS MATTER

Paul Graham created Y Combinator in 2005.

Y Combinator is the program that funded Airbnb, Dropbox, Stripe, Reddit, Coinbase and over 4000 other companies.

Combined they are worth more than 600 billion dollars.

When this man says something about how to build wealth, the entire world of business stops and listens.

NOTEBOOKLM JUST GOT A NEW FEATURE THAT CHANGES EVERYTHING!!

It reads up to 50 sources automatically and writes you a complete research report with citations in under 3 minutes.

The people who find this first are about to save hundreds of hours every single month.

Here is what it can do 👇🏽👇🏽 1. WHAT IS NOTEBOOKLM AND WHERE TO FIND IT

NotebookLM is a free AI research tool built by Google available at notebooklm.google

You upload any documents, PDFs, YouTube links, or websites you want to work with, and NotebookLM reads all of them and becomes an expert on your exact content.

You can then ask it questions, get summaries, generate reports, and create audio overviews from everything you uploaded.

It has been useful since it launched but the new Deep Research feature just made it something completely different.

You don’t need to spend weeks reading 50 PDFs.

Upload them to NotebookLM, then use Claude to turn that information into insights you can actually use.

Here are 8 prompts that can help compress 200+ hours of research into a single Sunday afternoon.

Bookmark this thread 🧵👇 Prompt 1: Use NotebookLM to Ingest, Then Hand Claude the Real Question.

Most people ask NotebookLM their hard questions and get shallow answers.

The smart move: use NotebookLM as the librarian, Claude as the analyst:

I just used NotebookLM to extract the following from [X SOURCES]: [PASTE NOTEBOOKLM SUMMARIES, KEY POINTS, OR EXTRACTS]

Context for what I'm trying to figure out:

- The decision I'm trying to make: [DESCRIBE]
- What I already know: [LIST]
- What I'm trying to learn: [QUESTION]
- The deadline pressure: [TIMELINE]

Now do what NotebookLM can't: think with me.

1. The 3 most important insights buried in these extracts (not topics — INSIGHTS)

2. The argument these sources are collectively making — even if no single one states it

3. The contradictions across sources I should resolve

4. The blind spot — what's MISSING from this research that I should look for next

5. The 1 insight that changes my decision

6. The 3-sentence synthesis I could share with a smart stakeholder

7. The single follow-up question worth ingesting into

NotebookLM next NotebookLM gave me the library. Now help me

Google owns one of the most powerful learning tools in the world.

It’s free. It’s been available for months.

Yet 95% of people still use it the wrong way.

Here are 8 NotebookLM use cases that can save you hours of time.

You have a topic you want to learn but don't know where to start.

Upload any documents, videos, or web pages about that topic.

Prompt:

"As an expert professor, explain this content to me from scratch, provide practical examples, and tell me what I should learn first."

Most people use NotebookLM the wrong way.

They only ask for summaries — and end up with average results.

Here are 10 advanced NotebookLM prompts that help you learn faster, think deeper, and truly understand your sources.

🔖 Save this for later. 1/ Practice with real-life situations

“Using only the uploaded sources, create 5 realistic situations where [topic] would be applied in real life. For the first one, explain the solution step by step, showing the reasoning, the concepts being applied, and common mistakes beginners make. For the other 4, only provide the scenario and let me solve them myself without revealing the answers.

After each response, evaluate my reasoning, explain what I missed, and show how an expert would approach it.”

I hadn't been able to focus for more than 10 minutes in 6 months.

Coffee. Cold showers. Focus playlists. "Dopamine detox" weekends. Nothing worked.

A friend pushed me to see a cognitive performance specialist. I expected ADHD screening, brain scans, maybe a referral for medication.

He didn't even ask me about my symptoms.

He looked at my iPhone and said:

"There are 4 settings turned ON right now destroying your attention span. 8 out of 10 patients I see have the same 4 toggles."

Me: "So my phone is the thing breaking my brain?"

He didn't answer.

Here's everything he showed me in the next 12 minutes (save this, your focus depends on it): 🧵 The first setting he pointed at: Notification Previews.

Every notification on my lock screen showed the full preview of the message.

He explained why that matters:

"Every preview is a micro-decision. Should I respond? Is this urgent? Who sent it? Your brain processes each one whether you act on it or not. By the end of the day, you've made 400+ involuntary decisions before you've made a single intentional one. Your prefrontal cortex is exhausted before lunch."

The fix:

Settings → Notifications → Show Previews → Never (or "When Unlocked" if you absolutely need them)

This single change does more for focus recovery than any productivity app ever built.

I changed it on the spot. Within 3 days, I noticed I was checking my phone significantly less because there was nothing to "preview" anymore.

Her iPad battery dropped to 78% in 18 months even though she barely uses it.

For context: a healthy iPad of that age should be at 90%+.

A few hours a week. Some reading. The occasional Netflix episode. She'd been "careful" with the device since the day she bought it.

She took it to the Apple Store expecting them to find a defect.

The Genius Bar technician didn't seem surprised at all.

"I see this every week. iPads degrade faster than iPhones and Apple has never publicly explained why. There are 8 specific things that quietly destroy iPad batteries. Most of them feel like the right things to do."

He opened her settings and walked her through every one.

Here's what she learned. 🧵 The first thing she learned: iPads die from being left alone.

This was the part that hurt the most.

She had treated her iPad carefully. She didn't drain it to 1%. She didn't blast fast chargers through it. She used it twice a week, then left it on her nightstand.

That was the problem.

The technician explained:

"Lithium batteries hate being idle at high or low charge states. When you leave an iPad sitting at 100% for weeks, the battery chemistry slowly degrades. When you leave it at 0% for weeks, it degrades even faster. The 'safe' state is around 50%."

iPads sit unused more than any other Apple device. That's exactly why they degrade faster.

The fix:

1. If you're not using your iPad for a week or more, charge it to **50%** before putting it away
2. Don't store it at 100%. Don't store it at 0%.
3. Check on it every 4-6 weeks and top it up to 50% again

She had been storing her iPad fully charged "so it would be ready when she needed it."

That habit was killing the battery.

Her Amazon orders were 18% more expensive than her sisters for the exact same products.

They lived in the same city. Had Prime accounts on the same plan. Were buying the same brands. Often within hours of each other.

Yet every single time they compared receipts, her totals were higher.

A laundry detergent her sister bought for $14.99 cost her $17.49. A pair of headphones her sister got for $79 cost her $94. A printer ink cartridge her sister paid $32 for showed up in her cart at $39.

STOP SAYING "HOPE YOU'RE DOING WELL."

IT'S THE MOST FORGETTABLE EMAIL OPENER EVER.

HERE ARE 10 BETTER WAYS TO START A CONVERSATION 👇 1. The "Inbox Bump" Trap

The Situation:

You sent a proposal 5 days ago.

No reply.

You type "Any update on this?" because it feels quick, polite, and harmless.

In reality, you're sending the exact same message they receive from dozens of people every week.

The System:

Most inboxes are overcrowded.

Generic follow-ups create zero urgency and zero curiosity.

When someone sees "Any update on this?", they know it requires effort to think, evaluate, and respond.

So they postpone it again.

The Corporate Translation:

"I need an answer, but I'm giving you no reason to prioritize me."

The Pivot:

"Thought I'd bring this back to the top of your inbox. Curious if you've had a chance to review it."

Why it works:

It feels helpful rather than demanding and gives the recipient a natural path to respond.

I asked Claude to improve my LinkedIn profile.

It didn’t just improve it. It made it a recruiter magnet.

Here are the 7 exact prompts I used: 1. The Headline Fix

→ "Rewrite my LinkedIn headline so it sounds like a top 1% operator in [industry]. Make it specific, results-driven, and impossible to scroll past. Give me 10 variations."

Her Apple Watch battery dropped to 78% after just one year.

She wore it daily. She charged it overnight. She used it like every other Apple Watch owner she knew.

Yet her battery had degraded faster in 12 months than her iPhone had in 3 years.

She took it to the Genius Bar, expecting them to confirm it was defective.

The technician ran every diagnostic.

"Your watch isn't broken. It's just been running 24 hours a day doing things it doesn't need to do. There are 4 default settings on every Apple Watch that hammer the battery overnight. Apple knows. They've known since the first Series 1 launched. They don't change the defaults."

She asked why.

He gave the same answer Apple Store employees have learned to give silence.

Then he opened the Watch app on her iPhone and walked her through everything.

Here's what he showed her. 🧵 The first culprit: "Always On Display."

This is the single biggest battery killer on any modern Apple Watch.

The Always On feature keeps the screen dimly lit 24/7 instead of turning off when your wrist drops. It looks beautiful. It's also one of the most aggressive battery drains Apple has ever shipped.

The technician put it plainly:

"Most Apple Watch owners think their battery is degrading. It's not. It's being used twice as much as it needs to be. The screen is on all day, even when the watch is just sitting on your wrist while you're working."

The fix:

Open the Watch app on iPhone → My Watch → Display & Brightness → Always On → Off

Or do it directly on the watch:

Settings → Display & Brightness → Always On → Off

Battery life on most watches jumps 30-50% the same day. The screen now turns off when you drop your wrist, exactly the way Apple Watches worked for the first 7 years they existed.

You lose nothing functional. You gain hours of battery life and years of battery health.

NOTEBOOKLM + CHATGPT IS ACTUALLY INSANE!!

NotebookLM turns your sources into research you can actually trust.

Then ChatGPT turns that research into posts, scripts, visuals, content plans, and repeatable workflows.

Here is the full content system 👇🏽 STEP 1: Understand The System

Most creators use ChatGPT like this:

“Give me 10 content ideas.”

That is why the output feels generic.

The better workflow:

NotebookLM = your research brain.

ChatGPT = your content execution engine.

NotebookLM helps you understand the sources.

ChatGPT turns the useful insights into posts, scripts, visuals, calendars, and repeatable systems.

The goal is simple:

Stop creating from random ideas.

Start creating from organized research.

A man saw his phone storage was ''full'' after 18 months but he barely had any photos.

He had deleted apps. Cleared messages. Removed downloads. The warning kept coming back every two weeks:

"Storage Almost Full.''

He went to the Apple Store ready to buy a new iPhone.

The employee at the Genius Bar held up a hand: "Before you spend a thousand dollars, let me show you something."

She opened Settings → General → iPhone Storage and shook her head.

"There are 7 things eating your storage right now. Apple ships every iPhone with all of them turned on. Nobody tells you they exist. Let's go through them."

Here's what she showed him in the next 8 minutes. 🧵 The first thing she pointed at: "System Data."

His System Data alone was using 24 GB.

He had no idea what System Data even was. Most iPhone users don't.

She explained: it's a catch-all category Apple uses for cached files, logs, temporary downloads, Safari residue, leftover update files, and dozens of other invisible things that accumulate over time.

Apple gives you no way to directly view or manage what's inside it.

The fix isn't perfect, but it works:

1. Restart the phone (clears short-term caches)
2. Settings → Safari → Clear History and Website Data
3. Settings → General → iPhone Storage → Offload unused apps
4. In extreme cases: back up and restore the phone (this nukes most of it)

He restarted the phone first. System Data dropped from 24 GB to 14 GB instantly.

10 GB recovered in 30 seconds.

Her android camera was taking worse photos than her previous phone.

She'd just upgraded from a 3-year-old Samsung to a brand new flagship.

The photos should have been a clear upgrade. Better sensor. Better lens. Better processor. Better software.

Instead, every photo looked worse than what her old phone produced.

Skin tones looked plastic. Backgrounds looked smeared. Low-light shots were noisy and over-sharpened. Group photos lost detail in faces. Sunsets looked artificially saturated.

She thought maybe the camera was defective.

She took it to a Samsung service center.

The repair technician opened the Camera app and ran a few tests. The hardware was fine. The sensors were calibrated. Nothing was broken.

Then he leaned back and said:

"Your camera isn't broken. It's been quietly sabotaged. Samsung enabled 4 features in a software update last year that degrade image quality across every model — and they never told customers. The default settings on your phone are making photos worse than what the hardware can actually produce."

He spent 10 minutes walking her through the fixes.

Here's everything he showed her. 🧵 The first feature ruining her photos: "Scene Optimizer."

Samsung's Scene Optimizer is marketed as AI that "intelligently enhances" your photos.

In reality, it's an aggressive post-processing filter that runs on every photo you take — boosting saturation, sharpening edges, smoothing skin, and "improving" the image in ways most photographers find unnatural.

The technician showed her a side-by-side comparison.

— Scene Optimizer ON: sunset oversaturated, sky unnaturally orange, foreground edges sharpened to the point of looking artificial
— Scene Optimizer OFF: same scene, more realistic colors, natural contrast, no plastic-looking sharpening

He explained: "Samsung enabled this by default starting with One UI 5. Most customers don't know it's on. Most customers don't know they can turn it off. The phone is editing your photos before you ever see them — and not in a good way."

The fix:

Open Camera app → tap the gear icon (Settings) → scroll down → Scene Optimizer → Off

Photos immediately looked more like real life. Skin tones became natural again. Sunsets stopped looking like Instagram filters.

His iPhone battery health dropped to 78% after just 1 months of use.

He took it to the Apple Store expecting a free battery replacement under warranty.

The Genius Bar technician ran every diagnostic. The battery passed every test. The phone wasn't defective.

Then she said something he wasn't expecting:

"This battery isn't broken. It's been worn down. There are 8 default settings on your iPhone right now that are aging the battery faster than they should and they're all on by default. Apple ships every iPhone with them enabled. Most customers come in here thinking the battery is bad. It's not. The settings are."

He asked the obvious question: "Why doesn't Apple turn them off by default?"

She didn't answer.

She just opened Settings and started walking him through them.

Here's everything she showed him in the next 10 minutes. 🧵 The first thing she pointed at: Background App Refresh.

It was set to "On" for all 67 apps on his phone.

She explained what this actually does:

Every app on your phone is allowed to wake up in the background every few minutes — silently — to check for updates, sync data, pull in new content, and "stay ready" for when you open them next.

Most apps don't need this. Most users don't realize it's happening.

Every wake cycle costs battery. Every wake cycle generates heat. Heat is the #2 killer of lithium batteries, right after voltage stress.

The fix:

Settings → General → Background App Refresh → either turn it OFF entirely, or set it to **Wi-Fi only** and disable it for individual apps.

Apps that genuinely need it: Mail, Messages, your bank.
Apps that don't: Instagram, TikTok, every game, every shopping app, every social platform.

He disabled it for 54 of his 67 apps. Battery drain dropped 22% overnight.

His android phone said it was ''out of space'' but he barely had any apps installed

128 GB of internal storage.

He had 24 apps. Maybe 800 photos. No downloaded movies. No music files.

The phone kept saying "Storage space running out."

He took it to a Samsung repair shop ready to trade it in for a higher-storage model.

The technician opened Settings → Storage and laughed before the customer even finished his sentence.

"Don't trade it in. Sit down. There are 7 things on every Android phone right now silently eating storage. Samsung, Google, OnePlus, Xiaomi they're all the same. Most users have no idea any of this exists."

Here's what he walked him through in the next 9 minutes. 🧵 The first culprit: "Cached Data" buried in every single app.

His cached data alone was using 19 GB.

Every Android app stores temporary files, images, thumbnails, page previews, video buffers to "make the app faster next time you open it."

The problem: most apps never delete this cache. Ever.

The technician pulled up the breakdown:

1. Instagram: 4.2 GB cached
2. TikTok: 6.1 GB cached
3. Chrome: 2.3 GB cached
4. Facebook: 1.8 GB cached
5. WhatsApp: 3.4 GB cached
6. Snapchat: 1.2 GB cached

That's 18.9 GB of "temporary" files the apps had no intention of ever removing.

The fix:

Settings → Apps → tap each app individually → Storage → Clear Cache

Or on Samsung phones: Settings → Battery and device care → Storage → tap each category → clear.

He recovered 17 GB in 4 minutes by clearing cache on his top 10 apps.

The apps still worked perfectly. They just stopped hoarding files.

GEMINI HAS BRUTAL FEATURES MOST PEOPLE ARE NOT USING 🤯
99% of people still use Gemini for basic prompts.

But Google quietly packed it with tools that can research, analyze files, build custom assistants, create apps, automate tasks, and turn messy ideas into real outputs.

You’re probably using less than 10% of what Gemini can actually do.

Here are 10 hidden Gemini features worth using 👇🏽👇🏽 1. Deep Research

This is one of the strongest Gemini features.

Instead of asking Gemini one question and getting a short answer, Deep Research can break down a big topic, search across the web, compare sources, organize the information, and create a full research report.

Use it for market research, product comparisons, competitor research, content ideas, business reports, travel planning, buying decisions, and understanding complicated topics.

This is not “Google search with a nicer answer.”
This is Gemini doing the research process for you.

🚨NotebookLM can now turn Articles, PDFs, and YouTube Videos into Structured Insights — like having an MIT researcher working alongside you.

Here are 10 prompts that will completely change how you analyze information 👇 1. Executive Summary (like a senior MIT researcher)

“Analyze all sources and generate an executive summary including:
→ Main findings.
→ Key insights.
→ Conclusions.
