Good student, what to do after school?

Hello everyone. I am a new senior in high school and am wondering to myself..what do I want to do? I can go almost any direction with my grades, I have faith in myself as well to do anything. but what? I want to travel but unless I miraculously get a job(I've tried and am still trying) I don't think I could. I love music, I play guitar and study jazz. I love the outdoors! I love biking and being outside in the sun. I love learning about ancient histories and civilizations. But the question is, what can I do, while I'm trying to find out what I want to do?
