I am an idealist. I don't know where I'm going but I'm on my way.
I'm not an idealist. I know we're not going to be living in a world that's peace and love all the time. But we can live in a world where we kill each other a lot less.

I'm still an idealist. My manager is always trying to talk me out of it, but that's just the way I am.
