Pack your show the night before the gig. In my experience I've found that if I leave the packing to the day of the show, I create unneeded and unwanted stress. I have also had several instances where I have neglected to pack props and in one case forgot my entire prop case! There is a calm the night before a show that allows me to truly focus on what I am doing and affords me the concentration needed to make sure that I have every prop prepared and in the case. I also print out my map(s), punch in the correct destination on my GPS and if I need my P.A.system I also set it by the door. The day of my performance is spent focusing on travel details to get there and preparing myself for the performance.
