Be yourself.
Your routines, methods and clothing are not your performance. You are your performance. I know this is not what the manufacturers of the latest tricks are telling you (Bill Abbott?!) but it is the unvarnished, naked truth. You should choose tricks you can put your "originality" stamp onto and that are inherently a part of who you are. How is it yours? How are you presenting it differently that anyone else on the planet? Will you still be performing this routine ten years from now (and loving it)? You don't have to re-invent the wheel but it would be nice if you painted it your favourite colour.
