Flying is accidentally the best ever environment for DEEP work and reflection.

Writers like @rickygervais do their best work on airplanes.

Here's 6 reasons why.

THREAD...
What looks like a bug - can often be a feature.

“A change of perspective is worth 80 IQ points.”

The restrictions we face on airplanes is what makes the experience so liberating.
AIRPLANE FEATURE 1 - HIGH EXIT COSTS

You can't find any escapes.

If you try to escape, you face death.

Negative incentives are built into the system.

"Incentives are a super power." - Charlie Munger
AIRPLANE ADVANTAGE 2 - NO INPUTS

There's no newsfeeds to refresh. No emails to reply to.

It's like knowing your heroin dealer is in a coma.

Boredom is built into the system.

Your monkey mind can't access dopamine - so it starts creating its own.
It is a distraction-free environment:

1. No socialising - You don't know anyone. No small talk.

2. No sound inputs - The engine acts as white noise.

3. No visual inputs - The seating structure means you see barely anybody.
AIRPLANE ADVANTAGE 3 - BARBELL EFFECT

If you're flying, you're on your way to an experience. (Flying to)

Or you have just had one. (Flying back)

Meaning your mind is racing with ideas.

There's a built-in barbell effect of ZERO stimulation right next to INTENSE stimulation.
Most of our days are spent in environments that have no barbell.

There's never 0% stimulation. And here's never 100% intense stimulation.

We are at a constant 50%.

There's no intensity. And there's no reflection.

Over time, life feels num
AIRPLANE ADVANTAGE 4 - NO NUTRITION THOUGHTS

You know every few hours someone will come round and offer you food.

Your mind doesn't have to make food plans.

And the awful food is a feature rather than a bug - you eat less and keep a clear head.
AIRPLANE ADVANTAGE 5 - UPRIGHT POSTURE

The awful seating on planes forces you to stay upright

Meditation 101 - It's easier to calm your mind when you have an upright posture

And if you try and decline your seat by 10% - there's negative social incentives built into the system
AIRPLANE ADVANTAGE 6 - AWFUL ENTERTAINMENT CHOICES

There are no algorithms powered by years of viewing data that knows what exact content to distract you with.

It's awful Hollywood flops and TV series.

Another feature that people think is a bug - it's easy to not watch em.
The ideal deep work environment should look and feel like an airplane:

1. High exit costs
2. Minimal external inputs
3. Opposite experience before/after to look forward to / reflect on
4. Nutrition taken care of
5. No access to distraction driven algorithms
6. Upright posture

Just re-read 'The Almanack of @naval'

Despite scraping his Twitter library for the @NavalBot, @EricJorgenson included a tonne of gems I'd never heard before.

Here's my favourite 17 highlights below...

THREAD...
"Making money is not a thing you do –– it's a skill you learn." - Naval

"You should not grind at a lot of hard work until you figure out what you should be working on." - Naval
"If you're looking toward the long-term goal of getting wealthy, you should ask yourself:

1. Is this authentic to me?

2. Is it myself that I am projecting?

3. Am I productising it?

4. Am I scaling it with capital, code, media or leverage? - Naval

Claude Shannon is the founder of Information Theory

His essay on creative thinking is criminally underrated

I've unpacked 2 of Shannon's ideas below

THREAD...
Shannon was the original theorist behind digitally storing and communicating information.

Without his work, I wouldn't be able to write this tweet you are reading.

Facebook, Google, Amazon, Apple, etc are all standing on Shannons giant shoulders.

Genius is an understatement.
SHANNON IDEA 1 - APPLIED OCCAMS RAZOR

"Eliminate everything from the problem except the essentials; that is, cut it down to size." - Shannon

"Almost every problem that you come across is befuddled with extraneous data." - Shannon

"How to Operate" is one of my favorite lectures

Keith Rabois (@rabois) breaks down OPERATIONAL EXCELLENCE

The principles are taken from the experience helping build Square, LinkedIn and PayPal

They are timeless

Here are 6 mental models from the talk

THREAD...
RABOIS MODEL 1 - BUILD A HIGH-PERFORMANCE MACHINE

"We used to joke that if Martians took over eBay, it would take 6 months for the world to notice." - Rabois

"Build a company that idiots could run - because eventually, they will." - Buffett
Rabois states that building a high functioning team or company is like building an engine.

It has 3 steps:

Step 1 - Build a beautiful conceptual whiteboard drawing of your engine at peak performance.

Josh Waitzkin might be the most INTERESTING person alive.

He doesn't have Twitter. And he barely uses the internet.

I've compiled my favorite 5 MENTAL MODELS of his below.

THREAD...
WAITZKIN MODEL 1 - DEPTH OVER WIDTH

His life so far:

1. Chess prodigy + National champ

2. 2x world champion in Tai Chi push hands

3. The 1st black belt in Jiu-Jitsu under Marcelo Garcia (GOAT)

4. He's now in an unknown ocean town mastering surfing + advising elite investors
The Waitzkin paradox:

He's achieved more WIDTH across disciplines in 43 years than most could in 100 lives

How?

His obsession with DEPTH over WIDTH.

His life is the testimony to deep work and singular focus.

He spends 5-10 years of his life dedicated to each craft

Thought experiment via Warren Buffett:

You have to invest in people you know.

You get 10% of their future earnings + happiness.

Who would you pick and why?

👇
1. @jkalms - Disgusting work ethic + drive. Goes the extra mile for people

2. @harrydry (@GoodMarketingHQ) - Unreal focus and nuanced thinker.

3. @alexayin - Best network builder + empathetic salesperson I know.
4. @connor_holly1 - Ultralearner that gets his hands dirty with the tactical. Learns in public.

5. @CathalUK - Puts the dots together on changing internet culture. Hyper rational and still hyper-creative.

6. Dr. Yusef (@PropaneFitness) - 10/10 humility + character. 100% trust
