I understood there's a huge difference between being an artist and working for some design agency. I didn't like the agencies, didn't like the job interviews, didn't like the people. My web design "career" was like Office Space the movie. I think I experienced the same kind of a career burnout as the protagonist of that movie.
I can imagine, in the future, doing pro web design only once in a while, only when I'm in the mood but 40 hrs/week-I can't take it.
