Don’t get distracted by shiny objects - Ray Dalio

You could have all the money you’ve ever wanted, a successful career, and be in good physical health, but without loving relationships, you won’t be happy . . . The good life is built with good relationships.

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.

Remember not to be overconfident in your assessments, as it’s possible you are wrong.
