Damn Thomas the Philosopher. Your area of interest is huge man. The "who am I" question is a fantastic journey but a bit of a mind fuck at times. If you have the time you definitely need to read some Descartes. But yeah I think it is a good direction but like Lee mentioned you need to reel this giant slippery bitch of a fish in a little bit before you can really grab hold of it. I am interested to see where you go with this.
One of my favorite modern ironies is that we have more ways than ever to share who we are and communicate with others around the world, yet we we try to communicate over the shortest distance, our own internal rumination, we are still as fucked as ever. I think the area of sport is a great form of personal identification. People ally themselves to sports teams as a form of identity. It is almost a way of belonging to tribe. I especially feel this being a football (soccer) fan in the States. When I run into another person with a Man U jacket or jersey I immediately feel a bond with them.
Anyway dude, the short answer to this all is watch the Jackie Chan movie, "Who Am I" it should answer all of your questions.
