Am I broken?

I don't stop thinking, I can't. My mind runs and runs and I can't do anything about it. I feel like nobody else thinks the same thoughts as I do. Am I broken? Why do I find myself questioning everything at every turn? Why is it that every time I learn something interesting or new I get a natural high? Am I addicted to learning? I'm supposed to hate school because I've been doing it for so long and everybody else does, but I can't get enough of it. If I could pick any career I wanted and get paid for it, it would be to go to school. Get degree after degree of pure knowledge, simply for the sake of knowing. Am I broken?
