Robert Greene in Mastery on why combining different skills gives you an edge:
“The future belongs to those who learn more skills and combine them in creative ways.”
Be impossible to explain.
Read old books. Make new mistakes. Sit alone for a week and see what shows up. Quit something that pays well to chase something that keeps you up at night. Get knocked down publicly. Get back up like nobody was watching.
Be obsessed and carefree at the same time. Disciplined and unpredictable. Steady and dangerous.
Be everything they said you couldn't be all at once.
You get one life. Don't spend it fitting into something smaller than you.
