I am currently seventeen and I really would like to go into the film/TV industry as part of the creative process. I have made a few short films in the past. Nothing along the lines of a spectacular spectacular (Moulin Rouge reference!

1. One area that I have very recently had a desire to go into in animation. However, there's one problem; whilst I have an Art GCSE and I have done some very minimal animation in the past (my film that I created incorporates a bit), I don't think that I'm currently employed enough. Call me arrogant, but I dropped Art as I felt angry with the whole system. Essentially, all I was doing (and would probably be doing for A-Level as well) was copying other artists' work. If I ever incorporated my style where possible, it pretty much got rejected and commented on negatively. Remember the brief flashback in the Brush with Greatness episode of The Simpsons (the one where Marge revives her talent for art)? Essentially, I am Marge. I'm really worried that what I did has hindered possibilities.
2. In addition to this, I think that I've applied for the wrong thing to do at university. I'm doing French and German come September, and I keep thinking that this was the wrong thing to do. I have some interest in these, but I can't help but worry that I'll wind up in a job that I really don't want to do due to taking these subjects.
3. I am worried that if I ever do get into the industry, I may end up unemployed. I've heard that jobs are scarce in a number of places in entertainment, and this scares me.
I am sorry for sounding like a gloomy fool, but I understand that some of you here are in the TV/film industry, so I'd really like to receive some advice from you guys over here.
