I think it's to do what's important to you, and having a lot of people - hopefully - listening to your work. It also involves being a credible artist, and being able to reach out to those who will buy into it for some other reason. But on a more personal level, success comes from having many close and strong relationships.
When I was around 12 or 13 my older brother had this friend who was a goth. He was dressed all in black... You know like super, super goth! I was just so drawn to that darkness and weirdness. I just wanted to rebel. And now that I think about it, rebel against what? I mean I have lovely parents and brother and things were always very great.
