I learned from my best colleagues: success is about trust. Nothing pays better dividends than being humble, being right a lot, and doing good work. This builds allies and allies build careers.

I learned from my worst colleagues: don’t assume that anyone will protect you from toxic or abusive people. You must be willing to protect yourself. When people come for you and your project, either be willing to throw down (metaphorically) or be willing to walk. Bad people often don’t have bad careers, and there is no justice.
