"Q. You touched on the point of confidence earlier. Can you elaborate?
A. For many guys, this is simpler because they’re not as over-invested in the question of “Do I belong?” Everything is not a test.

On the other hand, if you’re looking all the time for that kind of validation, you’re either going to be self-conscious or insecure, and neither of those is a recipe for success. What you want is the kind of inherent confidence that leads to grace. You want to be around people who are having fun and enjoying what they’re doing"
