We shouldn’t see our opinions as cherished possessions. We should treat them like everyday clothes. Look at the views in your closet that were trendy once. Discard the ones that look silly to you now. Wear the ideas that fit you today. Be ready to outgrow some of them tomorrow.

We pay too much attention to the most confident voices—and too little attention to the most thoughtful ones. Certainty is not a sign of credibility. Speaking assertively is not a substitute for thinking deeply. It's better to learn from complex thinkers than smooth talkers.
