If you like art, make art. If you think art school may help you do something you enjoy with your life, give it a shot. Many artists didn’t go to art school, but many also did. You got a looooong time before any decisions need to be made, so go try anything interesting, and then you’ll have wayyyyyyy more options to choose from.

as for things to do with art:
Graphic design and web design are really popular fields for artists. They also pay well, and you can make a very nice living if you have artistic talent AND a little business knowledge.

You could also be an architect, go to school for industrial engineering or a lot of other programs in colleges that involve design. (See the majors at schools like Georgia Tech, Cal Tech, Virginia Tech etc.)

Hope that gives you somewhere to start!
