Is it important to "project" confidence in your job?

I guess I always thought my "brilliance"would get me ahead

To be honest the idea of managing people makes me ill. Why would I want to have a meeting and ask people what they are workng at?

I guess it was never meant to be, me and management.

I was always ambitious and I'm well paid, but that management side of things never interested me. Better to know oneself and ones limitations.
