Carl Sagan was a brilliant astronomer, author, and professor.

He's well known for being the presenter of the popular PBS series "Cosmos."

Here are some of my favorite thoughts on books from the show.

(thread) 🧵
1/

• Humans are the only species on the planet that have learned to stockpile enormous amounts of information outside our bodies.

• Today, we call these communal memory systems libraries.
2/

• The Assyrian library of Ashurbanipal had thousands of clay tablets.

• The library of Alexandria had almost 1,000,000 papyrus scrolls.

• Modern libraries, such as the New York Public Library, have around 10,000,000 books.
3/

•"If I were to read a book a week for my entire adult lifetime, I would have read maybe a few thousand books, no more. The trick is to know which books to read."
4/

• "What an astonishing thing a book is. It's a flat object made from a tree with flexible parts on which are imprinted lots of funny dark squiggles. But one glance at it and you're inside the mind of another person, maybe somebody dead for thousands of years."
5/

• "Across the millennia, an author is speaking clearly and silently inside your head, directly to you”.

• "Writing is perhaps the greatest of human inventions. Binding together people who never knew each other."

• "Books break the shackles of time."
6/

• "A book is proof that humans are capable of working magic."

• Some of the earliest authors wrote on bones and stones. and date back to 5,000 B.C.

• Then in the 2nd-6th century in China, paper, ink, and printing with carved wooden blocks were all invented.
7/

• Around 1450, moveable type was invented.

• Before the Gutenberg printing press, there were about 10,000 books in all of Europe.

• Fifty years after its invention, there were 10,000,000 printed books in Europe.

• "Learning became available to anyone who could read."
8/

• "Suddenly books were being printed all over the world. Magic was everywhere."

• "Books permit us to voyage through time. To tap the wisdom of our ancestors."
9/

• "A library connects us with the insights & knowledge of the greatest minds & the best teachers, drawn from the whole planet and from all our history to instruct us without tiring & inspire us to make our own contributions to the collective knowledge of the human species."
10/

• "For the price of a modest meal, you get the history of Rome."

• "Books are like seeds. They can lie dormant for centuries but they may also produce flowers in the most unpromising soil."
11/

• "Books are the repositories of the knowledge of our species & of our long evolutionary journey."

• "Libraries in Ancient Egypt bore these words on their walls: Nourishment For The Soul. And that's still a pretty fair assessment of what libraries provide."

RIP Sagan 🙏

Reading Tip:

• Size Doesn't Matter 📏

As the old saying goes, it's not the size that counts, it's how you use it.

(get your mind out of the gutter people, we're talking about books here)

1/ Small Packages Can Pack A Punch

There are some readers that look down on short books.

They view books that are ~100 pages as a short story & not a real book.

But we should thank these authors for trimming the fat from their books & leaving us with only the best parts.
1/ (continued)

What short books lack in length, they make up with depth.

Don't believe me?

(thread) 🧵
0/ Intro

I'm not a social media growth expert or hacker, but I've built up an audience of 100k+ followers:

• Instagram = 79k

• Tiktok = 4k

And have noticed some common fundamentals laws to growing on a social media platform. Enjoy!
1/ Every Social Media Platform Is Its Own Country

Every country has its own culture, the same is true of every social media platform.

Users consume content and behave differently, just as people eat different foods and follow different customs.

I've summarized 400+ podcasts for @podcastnotes.

Here are my top 10 favorite podcasts of all-time.

(thread part 2) 🧵
10/ @SPressfield on @jaltucher

If you're a writer (or an artist in general) this is a MUST listen.

Pressfield is a living legend and shares a ton of advice on not just writing better but also living better.

It's a super entertaining and educating podcast.
9/ @kobebryant on @patrickbetdavid

This is of the last podcasts by the late great Kobe Bryant.

Kobe shares basketball advice, how he developed an alter ego, why he got into storytelling, tips on the craft, and much more.

Listen to learn about the mindset of a champion.

I really believe the 25x250 Reading Challenge is one of the best things I've created.

Here's why:

(thread) 🧵

[PS: scroll to the bottom for a FREE and UPDATED version of the reading challenge]
1/

As I mentioned before, the 52 Book challenge is flawed. It:

• Punishes readers for quitting books
• Punishes readers for picking long books
• Incentives quantity over quality reading
• Doesn't reward readers for reflecting or taking action on what they've learned
2/

The 25x250 Reading Challenge solves all of these problems:

• It doesn't punish readers for quitting books
• Nor does it punish readers for picking long books
• It rewards readers for reflecting and taking action
• It encourages people to read BETTER, not just read more.

Reading books will help you win the battle.

But taking action will help you win the war.

Reading Tip:

• Have an Action Day 💥

1/ Reading Is Only Step 1

If you're reading books, that's fantastic.

You're gathering helpful information and creating more accurate mental models of the world.

BUT...

Books are only part of the solution.

You need to reflect on what you've learned and apply it to your life.
2/ The Self-improvement Process

There are 3 parts to becoming a better person:

1) Reading
2) Learning
3) Growing

I cover this in my 25x250 Reading Challenge, but for now I want to do a deep dive into the last part:

• Growing

A reading tip inspired by @elonmusk

(thread) 🧵
In a Reddit AMA, someone asked Elon how he's able to learn so fast.

His response?

"It is important to view knowledge as sort of a semantic tree--make sure you understand the fundamental principles, ie the trunk and big branches, before you get into the leaves/details." -Elon
"View knowledge as sort of a semantic tree..."

That got me thinking, and I realized that it's the same for books.

There are 3 types of books (at least when it comes to non-fiction):

• Trunks 🌳
• Branches 🌿
• Leaves 🍃

Here's what I mean...
