I really appreciated this advice. It's vague enough that if it relates to your life, you'll probably see how when you hear it.

I think I can apply it to both my work life, thinking about times where I overworked myself at a company where nobody else cared enough, and to my personal life, thinking about times where I invested myself fully into relationships where it wasn't certain to be requited.

Detachment, objectivity, negotiation, game theory.
