Probably the first key to success is knowing how to spell 'restauant' but i'm just kidding you.
Ask lots of questions. Keep your equipment clean and maintained always. Buy good shoes.
Pick one type of cooking that you really love and master it. Know enough about everything else to work a station or cover someone else's.
Know that a cook, a caterer, a camp chef, a home cook, a banquet chef, a pastry chef, a baker and a chef-owner are completely different people.
Guard your hearing, I can't hear very well and it sucks in a lot of open pass kitchens. Don't destroy what God gave you to work with.
I've seen a lot of cooks I really admire and respect get into serious trouble with drugs and booze. Know it is a risk in your environment and stay straight.
I hope to stage at your new kitchen some day. : D
