Hehe, I hear you guys.
I for myself never had the idea to become something like a concept artist but I always wanted to work as a creative graphics designer (as I do now) and I have to say that my skills in drawing and the general idea for design, that we developed helped me getting into this position.
You might not become a concept artist but doing other stuff that is at least remotely connected to our hobby really gives you a lot.
I love going to work, because I know I can do stuff that I like there.
I'm creating animations in After Effects, design user interfaces, create designs for presentations on the ipad and sometimes even my drawing skills are needed to do illustrations.
After all we have a nice hobby and you can make your hobby your job, even outside of the games and movie sector.
