I suggest putting art aside as a hobby. Realistically? You will not get far. Yes, as
>>2 stated, you CAN get somewhere. But do you know how long and hard Walt Disney had to work to try to get accepted and or do wutever the heck he did?
Facts are that someone is always going to be better than you. Younger or older. It would be a wiser decision to go to college, learn something, get your wages, and if you're still feeling up to it, go to art school. But right now, you don't have the money, and the chances that you will become famous and wealthy while you're alive? Not very many. :/
I'm sorry, but it's a real aspect of life that some people haven't yet grasped. You can go for it, go to art school, but if you don't get paid as much as you wanted....don't come back to tell us what horrible decision you've made. Because, for one, you probably won't be able to afford a computer or internet, or barely afford an apartment. :U good luck, make wise decisions.
