I studied psychology for a couple of years as a personal hobby, so you start learning about people and listening to your intuition, like when you you're feeling that people are not being entirely straight with you.

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.
