When did I suddenly start relying so much on others and thinking so highly of what other people say?

I remember I used to do everything on my own - I didn't care what people thought about who I was, what I said, and what I did. Lately I've noticed that I really have been changing for people. Maybe this is a good thing, maybe this is a bad thing...

But I do know that for the rest of December, I'm not gonna care what anybody says or what they think of me. I'm gonna do my own thang.
