Worth staying in Austin?

I started Physics grad school this Fall, but I have recently considered dropping out in order to find a job in industry (I'd like to work at a startup). I know this could look really bad to employers, but I just have no motivation to continue my studies

Recently I've been working on a programming project on my own (a sort of video game), as a way to improve my programming skills, and I've been working on it with alot more motivation than studying for my Physics classes. I'm still fairly new to programming so I can't say I'm committed to programming over Physics yet

Anyways, the semester is almost over and I have to make a decision soon as to whether to move back home (Los Angeles) or stay in Austin to find a job. Ideally, I would like to work as a programmer for a computer software startup. That is because after reading Paul Graham's essays, I think I'm willing to take the risks involved in running my own business or joining someone else's startup.

But my programming skills aren't that great and my statistical analysis software skills aren't either (I've only used SPSS minimally). Also, I have no idea as to what kind of startup I'd like to work for. I'm not interested in Iphone apps, social networking, etc. But analytics seems pretty interesting.

Would I really be missing out on alot of opportunities if I moved back to LA instead of staying here in Austin?
