Here's a thought: you can choose, if you like, to have a career that takes you to work with people who are cleverer than you at what you do. (Logically in a given field there must be one person who can't do that - but even that person could achieve much the same effect by switching fields every decade or so! You are highly unlikely to be that person, anyway; there are many people who feel as out of peers as you do while they are students.) This is probably a cheering thought. You might like to think about what attitude you'd like to experience from those people who are better than you at what you do, and cultivate it in yourself towards others.
