Following up on what darthviper107 mentioned,
Dont do that. Whatever you like doing most, thats what you should focus on learning. If you arent interested in art, you wont become a good artist. You can familiarize yourself with many of the aspects of game production, but you wont ever be able to become a master of all. Remember, jack of all trades etc.
So its important for you to know, what part of this do you want to be.
