How to be a successful non-rev? Two things immediately come to mind: Back-up plans and patience. You will always need both. Never non-rev anywhere you MUST be at a certain time (murphy's law will come into play then) and always have a back-up plan both for getting there and coming back. While you should let flight loads guide you, don't always let them deter you from trying. I have personally made it onto a flight (with 4 people) that was oversold by 30 and we were numbers 26-30! Make sure you ask about an airline's dress code and be especially sweet to the gate agent. Don't harrass them to find out whether you will get on. They'll call your name if you make it. Please be prepared to board immediately after your name is called. Learn to pack lightly and make sure your carry on meets the size (and weight) requirements.

Let's see, I can't think of anything else right now. If you need further help, we are always happy to give advice around here.
