If I had that choice, to travel around, I certainly would do that.
But that is what you want now and what you will want in the future...And there's a thing you can't miss: money.
I can't see another way to get it any than having a job. You can have a job only having high school, or you can search for something better going to college.

I'm in medical school and believe me, it was really though to choose to be here. I could enter anywhere, I didn't like anything, and what I liked the most didn't assured me a job. So I end up here. And after four years after I have finished high school I still wonder, what if? I still think I'm not supose to be here.

Choosing something you don't know how will be it's like a shot in the dark, but is better give it a try than don't. What my parents and family used to say to me, you can change your decision any time...after you complete your graduation you can always do a different one.

Study can be realy hard, but maybe in the end it can be worth.
