I need help pronto. am so lost and i need advice?

ok so i went to school for I.S.S (information system security) thinking that this is what i wanted to do. but i soon saw that i was getting tired and i felt that i wasnt getting anywhere. and it wasnt what i really wanted to do. so now am in debt (i know what a stupid thing to do) so am paying off my school loans and am stuck i want to have a career but i cant decided what i dont want to make the same mistake agian the problem is that i dont know what i want to do. i like doing all sorts of things i just cant figure out what my hobbies are and what i would want to spend my life doing am only 22 but i feel that time is running out and i have to do something fast. my main intrest right now is reading, photography, i dont know if there is anything i can do that will help balance this two things out.
