Thanks all for the replies. What I am still just unsure about is how much I would be using drawing and such in one of the before stated jobs. I mean would I be just drawing my ideas first to then show the other people working on the project? (Wouldn't have to be the best art, just get my idea across) Or would I be having to pitch ideas with my drawings. (Would have to be high quality art)
I have started to practice drawing but it still feels as though I will never be good at it. I am just feeling now as though my inability to draw will limit, if not destroy my chances of getting a job doing 3D animation/modeling.
