Yeah. I can relate to you. I'm going to finish school in a few months and go to college. My problem isn't exactly knowing what I want to do, but it's the will to try and execute it. I want to be an actor. Preferable a voice actor, for video games and stuff. The problem is that I have no idea of knowing if I'll be successful in this department, so in case I try and fail I need to have something to fall back on.
Thats where the trouble sets in. Sure, I don't need to go to College to become a voice actor, I need to go to acting school; which is expensive and Ireland isn't exactly charitable in terms of employment now. The only thing I can do is go to College. You could spend your entire life trying to learn what you're good at, the trick is to try everything until then. In school I tried writing, acting and video editing and I liked all of them. So I guess the only choice I now have is to go to college based on those skills.
What am I doing? Hopefully Arts,with English,Sociology and Psychology as subjects. In the meantime I'll do whatever acting I can, and learn and enjoy stuff in college as well, so thats all I have planned. My problem is I'm not 100% sure what to do with myself if this acting thing doesn't work out (and it might not work out).
I have some ideas though, being a Film/Music/Video Game Critic, as I love all 3 of those mediums. I'd also like to write scripts for films and even Lecture English! Silly isn't it?
Ok, waffle aside, I would say just to try anything you haven't tried before.Or look into more detail of the things you already like. Everyone is good at something, it's just a matter of finding out what it is.
