Tenev accepts negative feedback and tries to improve
Original excerpt
You could tell him almost anything, even if it’s really negative, and he’ll say, ‘I’ll take that feedback.’ And he’ll think about it and try to improve based on it. He doesn’t hold a grudge. He won’t skip your next meeting. He loves truth-telling. He loves data and information. He really wants to understand your view. It’s part of his scientific process—his first-principles approach to everything.
