My principles.
Time and work
Money should be used to buy time, not things.
You should have a wide funnel, and a tight filter. Let anything in to check it out, but throw it out quickly if it’s not worth your while.
The best way to know what you think is to write it down.
You shouldn't be proud of what you consume, only of what you build.
Despite how it may appear, no one has everything figured out. We're all playing this game for the first time.
You'll learn a lot more by building the wrong thing than thinking about the perfect one. Start early, refine, and know when to pivot.
Let many things interest you, but few things claim your attention. One serious bet at a time.
Not all valuable time needs an output. Leave room to walk, wander, and be bored.
Family & relationships
Raise children to be curious, generous, resilient, and active.
Be someone your children choose to spend time with.
You can't take anything with you, but you can choose what you leave behind.
Try to not shy away from making the hard decision or saying the difficult thing, but always do both with kindness.
Health
Avoid sugar before lunch.
Work to be fit enough to never have to say no.
Drink only water in the first waking hour.
