This is actually a very good point. Know when to be bold and confident, and know when to keep your mouth shut. I've actually found a good heuristic to know when to do which. If I'm uncomfortable and insecure, it's time to be bold. And if I'm sure I'm right and the other guy's wrong, it's probably time to shut up and listen. It basically comes down to doing the opposite of my emotional response. It's not easy, but when I follow that guideline, things tend to work out better.
