If you like something because you think other people will like it, it's a sure bet no one will.
Most doors in the world are closed, so if you find one you want to get into, you damn well better have an interesting knock.
Things you think are important aren't, and things you think aren't important are.
Don't shit where you eat.
Lean into it. The outcome doesn't matter, what matter is you're there for it.
Never sleep with someone who has more problems than you.
My personal addition:
Write what you want to read.
