Elon has one question he asks every morning. It's changed how I think about work.
“How can I be useful today?”
Not: how do I grow my career. Not: how do I make money. Not: how do I look productive.
Just: how can I be useful?
Here’s how Elon thinks — and the mental models worth stealing:
The Utility Formula
Elon measures everything by a simple equation:
(Number of people helped) × (magnitude of help per person) = utility
This is his definition of success.
A product that changes 10 lives deeply is just as valuable as one that makes a million lives slightly better.
Not every product needs to change the world. It just needs to make someone’s life better.
Why People Start Companies Wrong
Most people start companies because:
- They want to be an “entrepreneur”
- They see the money
- It sounds cool at dinner parties
Elon’s filter is different.
“What is the useful thing you could build that you wish existed in the world?”
He didn’t analyze risk-adjusted returns. He found things that needed to happen. Then he made them happen.
→ If your money was lost trying, was it worth it? Elon says yes. That’s the test.
The One Trait That Separates Entrepreneurs
Charisma? No. Vision? No. Fundraising ability? No.
Obsessive compulsive nature about product quality.
That’s it. That’s the one.
If you like what you’re doing, you think about it even when you’re not working. The product lives in your head 24/7. That obsession is the edge.
Physics Is Law. Everything Else Is a Recommendation.
Elon uses first principles to fight the biggest trap in business: wishful thinking.
We all do it. We filter out information that contradicts what we want to believe.
His solution: always assume you’re losing, even when it looks like you might win.
Not pessimism. Anti-complacency.
→ Reasoning by analogy = doing things because others do them → First principles = asking what is actually true, from scratch
Most decisions are made by analogy. For important ones, that’s fatal.
The Fear Hack Nobody Talks About
Elon doesn’t claim to be fearless.
“It is normal to feel fear. If you don’t feel fear, you definitely have something mentally wrong.”
The insight: people don’t fear things. They fear looking at things.
Most people feel fear → avoid thinking about it → fear grows → paralysis.
Elon’s way: look fear straight in the eye. It disappears.
The mission becomes bigger than the discomfort.
The Warning He Actually Gives
Here’s what nobody quotes from Elon:
“I guarantee you don’t want to be me.”
Long periods of pain. Constant fight for survival. Self-torture at a level he calls “next level.”
He’d tell his 20-year-old self to occasionally stop and smell the roses.
The lesson: don’t try to be Elon. Try to find work you’re compelled by. There’s a difference between compulsion and performance.
The Question That Changes Everything
Start tomorrow with this:
“How can I be useful today?”
Not productive. Not busy. Not impressive.
Useful.
The measure of a life well-lived isn’t the resume. It’s how many people you helped, and by how much.
That’s the whole game.
