Mingle with people and you'll soon realise there are things they're better at than you. That's normal, and hopefully there are things you're better at yourself!
The key point is to work with people who are good at things you're not good at, even though it feels strange. You may prefer to know everything, be the best, impress others.
Beware however of surrounding yourself with people who'll flatter you too much and kick the others out. As a recruiter, you should hire people who complement your existing skills.
