Do not go to art school-but don't just aimlessly "go to college" either, which is a huge mistake a lot of kids make once they realize that the art schools fail their students more often than not.

Commit to art, but disregard the credentialism and ceremony of a college degree because it's worthless in this field. Seek out local art classes (google maps "atelier", "art class", "illustration", etc.) or in person mentorships. There are inexpensive and free resources online managed by artists better than those you'll find at most schools, too.

If you haven't been drawing compulsively, religiously up until now and you're thinking two or even four years of a $40,000/year school is going to bring that out of you, forget it. Start hitting it hard NOW and maybe if you don't make it under your own terms by 22-24 you can think about school.
