I live for my family, because I know they'd be sad if I died. I live for my dog, because I love my dog; he's the best dog in the world (and better than quite a few people I've met). I live for my girlfriend, because I love her, and she told me not to die. And I live because I'm a space geek, and I hope that I'll get the chance to actually go to space someday (which explains my major).
