Get a good ART education. Not hippie concept art everything goes education, but something that'll push you, so you'll learn not to just "express yourself", but also develop a firm grasp of anatomy, perspective, composition, lighting, everything. In other words, become a good artist. The really good ones can get jobs anywhere, in games, in the film industry, in illustration. You'll only be restricted by your skill. An artist that does concept art for games doesn't really use anything special or different than all the other regular artists. I just think that they probably benefit if they have a jack of all trades approach, so they can do different styles. But thats a big advantage in any field, really.
