I don't know what to do after high school ?

I have 2 years left and I'm clueless. I have had many teachers try to help me and I still find nothing. I have a interest in horses and music. But both fields are hard ones to make a living on. I say I have this interest but at the same time it comes and goes. I would like a traveling job. I have nothing to stay where I'm at for. I'm hard working and if I really want something I will work hard to get it. I thought about the military but I have a small Handicap. Maybe I just haven't found what I'm really into yet. I really like science. I don't know, I'm jut confused and my parents think i'm going to be some bum because I don't have any goals.
