anyone in the film industry?

I know the film industry is super cut throat and hard to be successful but I really can't see myself anywhere else. Academics aren't my thing. I love fashion so I would love to be a costume designer but the pay is soooo low, I would also like to be an editor either for movies or tv which the pay isn't much better that I've read. I know it's super tedious work but even for school movies we make I always volunteer to edit them because I love putting my creativity toward that. Money is pretty important to me, I want to be able to support myself and live comfortably but I also want to follow my dreams. I already live in LA and it's crazy expensive, I want to be able to do it on my own. I'm going to college in New York I'm already commited and majoring in Film and Television and hopefully minoring in Fashion. If anyone has any advice for me please comment.
