your comment was probably in jest, but honestly, hiring is really really hard. no matter how hard you try to screen, test, and filter candidates, applicants and recruits, you never know for sure what performance you are going to get, or how this performance will change over time. the absolute hardest is personal fit within a team (back to a players like a players), but if you have high performers competing instead of working together you get that herding cats syndrome.
to expound on that, A people are not usually afraid of competition or a challenge.. often welcome working with people smarter, more talented or productive than themselves.
B people are more interested in protecting what they have, and to keep what you have, you may be able to out perform a C player, this the interst in hiring C players.
honestly, I think everyone is self conscious, or a little afraid from time to time, and that is OK, you just need to be able to get past it, have a little Faith in your abilities, work hard and don't expect raises, praise or titles (which ever your favorite flavor of sucess us) until you work hard and accomplish something.
