The good thing is you have so many doors open now. Do whatever. You're young enough to pick up any hobby or career. Don't think about whether it's financially worth doing or if you're on some "mission" or "purpose". Don't think about whether it's safe or unpopular.
Sometimes the most fulfilling things are inherently worthless. Learn an instrument, buy a motorcycle, make a painting, become a scuba instructor, run a marathon, try drugs, move to another country, sit at a park/cafe and talk with people - you get the picture. You'll find something that clicks, just get out of your checklist view of life.
