Hi aarandir,
First I would be extremely careful with the money and make sure you have it in some low risk savings account earning as must interest as possible. I think if you set out to start your own business you will quickly realize 30k is really not that much money at all. My advice would actually be to get a full time job and work for a few years in whatever industries or passions you may be attracted to. Get some business / life experience save up a little more money and really plan out how you are going to spend that money and turn into more. It sounds as if you are bit emotional right now and that is the worst time to make financial decisions. You are still so young and have the world ahead of so there is no real need to rush into anything. While you work and learn more about the world you can plan and prepare to set out on your own as an entrepreneur.
