Well, I graduated. And went to do something that almost has no connection to what I graduated. :-) If you want something that will make money for you almost immediately, go with the cars. You will at least be able to work in a garage. But if you want to do photography, take care to work on it. As cyn said, find somebody who will show you what to do, even if it's just one or two days a week. Carry a camera, take photos, read about it. Photography, like any other visual art, will not start making moeny immediately.
