Selfishness

Have I really been selfish all my life? I mean, I realize everyone is selfish to a certain extent. It's inevitable. But looking back at myself I'm starting to think my nice side is just a guise, hiding the fact that I'm just out to advance my position(?). This is all unintentional. But...how can it be if I'm doing it consciously?

I hope I don't scare my girlfriend off because of this. I gotta watch how I act..
