Bro, relax for a second, it is all good. ANYONE that has competed knows what you are feeling. You have already put in countless hours, but you begin questioning yourself. This usually happens right around 4 to 6 weeks out. LOTS of guys quit at this point (I'm talking about first timers here, vets go through the same anxiety, but are less likely to quit since they already knew what they were getting into). My advice... You have decided to do the show, so you should do the show. If it's the last one you ever do, then so be it, but at least you followed through (not to mention placing yourself into the very small percentage of the population with enough balls to get on stage.) Hit it hard this last 6!
