I've been curious, as to all the artists here. Who is actually a graphic designer, and who does it for a mere hobby?

I'm thinking about changing my career paths and I'd like some feedback.
I really don't want to be a mechanic, but I don't want to hit a dead end in graphic designing.

I want to know how far it can go, as to animation, prints, advertisments. etc.

If any of you guys can peak my interest in graphic design once again, I'd appreciate it.
