First, radically accept human nature.
Then, learn to create value for society by combining foundational knowledge (communication and first-principles thinking) with specialised, cutting-edge knowledge.
Apply this knowledge creatively to solve problems that nobody else in the world could've tackled.
Use these unique solutions to help other people (and hence build a solid reputation).
Have irrationally high levels of agency, and unreasonably high faith in the process of compound interest.
Ignore the people around you who get “lucky breaks”.
Extend your time horizon as far as you can into the future.
And if you do all this, you’ll never have to worry about being replaced (for as long as replacement is a worthwhile worry).
There’s only one question left: what’s next?
