GO TO COLLEGE AND THAT IS AN ORDER!
Seriously, like you I wasted time not going to school. I'm 29 now and finally focussed in school and I know what I want to do.
Please, for your own sake do not waste as much time as I did. It doesn't matter if you do not know what you want to do yet. You will soon enough, if you keep going to school.
Get all of your general ed. courses out of the way because those are courses you have to do no matter what major you choose.
Good Luck! AND STAY IN SCHOOL!
