I added to some one's answer to a similar question earlier and will offer up the same idea that I gave there: Car Wash. You could work as one of the folks that dry off and/or detail the vehicle after they come out of the wash. Just a suggestion. PEACE!!!!
That's a tough one buddy,it's hard for us at any age now. Try Wal-Mart,Target ect., try to get in a dept.you enjoy like auto or lawn and garden and learn things that may help you find a better job in that area when your a little older.
