struggling gives one strength. - Ray Dalio

Beware of statements that begin with “I think that . . .” Just because someone thinks something doesn’t mean it’s true.

You only have so much time and energy; make sure you are investing them in exploring the problems that, if fixed, will yield you the biggest returns. But at the same time, make sure you spend enough time with the small problems to make sure they're not symptoms of larger ones.

I have found it helpful to think of my life as if it were a game in which each problem I face is a puzzle I need to solve. By solving the puzzle, I get a gem in the form of a principle that helps me avoid the same sort of problem in the future. Collecting these gems continually improves my decision making, so I am able to ascend to higher and higher levels of play in which the game gets harder and the stakes become ever greater.
