The really good guys are middle aged and fully confident, but starting to get over the hill a bit probably.
Quotes like that will prevent you reaching middle age!!!!!
Now back to the poster, just realize that everyone is worrying about how to do things and are they getting it right, some just exude confidence better than others. If they are really confident, be afraid, they normally make the biggest cock ups, a bit of fear is always good for you. Finally you never stop learning even if you are over the hill!!
