I guess I do have a childlike sense of fun, and although I still have my dark days, I'm generally an optimistic person. The way things have gone in my life, sure, I could have been a bitter person. But I just find bitter people really un-fun, you know? And who wants to be that person?
I'm an optimist in the sense that I believe humans are noble and honorable, and some of them are really smart. I have a very optimistic view of individuals.
