Sometimes it makes more sense for me to think that I'm not a rational being, I'm an animal with a rational brain glued on top.

If you do a "5 Whys" type thing, there isn't really a reason to live. It's just an instinct. So I can say, I'm a hedonist, I live because life pays off eventually. No big deal.

I don't think rationality is opposed to anything like love or sentiment. I just like feeling good. Rationality is a tool I can use to feel more good, if I want.
