For me, every day is a new thing. I approach each project with a new insecurity, almost like the first project I ever did. And I get the sweats. I go in and start working, I'm not sure where I'm going. If I knew where I was going I wouldn't do it.
My last real job was selling air time for CBS affiliates. I quit that when I was 28, and that was the last real job I had. I beat the system. I've been able to do this full-time for almost 15 years.
