12 lessons on the human brain: 1. The brain isn't just a big bunch of mush

"It has structure. It has organization. The different bits do different things."

"When Bob had this big lime in his head, he didn't just get a little bit stupid. His IQ would be unchanged. He lost a very specific mental ability."

"That's good news for science if there's part structure, there's at least a place to start."

He just refused to waste his remaining time on self-pity.

→ "This is what competitors do"
→ "This is industry standard"

First principles asks:
→ What are the fundamental truths?
→ What can I build up from there?

Analogy is safe.
First principles is how you find the counterintuitive.

He broke down:

• Product-market fit
• Team building
• Market selection
• Competitive moats

Here are 14 lessons worth more than a $200K MBA:

1. 80% of startup success comes from one thing Build a product so good that people spontaneously tell their friends.

That’s it.

If users don’t evangelize for you, nothing else matters.

Rule:
Word-of-mouth isn’t a growth tactic.
It’s the proof you built something great.

He broke down how:

• Create X dollars of value
• Capture Y% of that value

Most people assume X and Y are linked.

They’re not.

You can create enormous value and capture almost none.
You can create modest value and capture most of it.

Monopolies excel at both

Carl Jung said: “Until you make the unconscious conscious, it'll direct your life & you'll call it fate.”

Feeling stuck? It’s not bad luck.

It’s your shadow controlling you. Most run from it & never break free.

7 Jung principles that reveal the hidden forces driving your life: 1. The Collective Unconscious: You are not a blank slate

Jung believed that deep below your personal memories lives a collective unconscious, a psychological inheritance passed through generations.

It contains universal themes, instincts, and symbolic patterns shared by all humans.

It’s why myths, dreams, and hero stories feel familiar even across cultures and centuries.

But no one talks about Ken Griffin.

He built the world’s most profitable trading empire by staying invisible.

Here’s how a math nerd from Harvard became Wall Street’s real kingmaker: It started with a satellite dish on a Harvard dorm.

Ken Griffin was 19.

While his classmates studied for finals, he was building a hedge fund from his dorm room.

He convinced a family friend to give him $265,000.

Then illegally bolted a satellite dish to his window to get real-time market data.

It manages over €7.2 trillion in assets across 14,500+ funds, more than Germany’s GDP, in a country smaller than Rhode Island.

How did it pull this off?

He reinvested profits, undercut competitors, and built oil pipelines when railroads tried to squeeze him.

People called him a “robber baron.”
