I wanted to be a musician because music was what I enjoyed to do the most. When I tried to do it professionally though, it became a job and I lost all the reasons for why I enjoyed it in the first place.
Then I switched to something that I also enjoyed but was also something I felt I could succeed in which was computers.
That being said, after completing my degree I short of understood why the university made me take all those core classes that I hate. Even though most of them sucked I had a few that introduced me to other fields that COULD have been an alternative for me.
Looking back, I really wish I had taken geology sooner in my education so that I could have done more, perhaps minor in it. My only regret I think is that I waited until the end to take many of my "extraneous" courses.
This is also in contrast to other fields that I dabbled in. I generally liked history before college but like music, I found it to be more of a chore in many circumstances to study it in strict academia. Even though I liked geology very much, I absolutly hated physics and chemistry which I had tried prior because I thought they would be more "usefull".
My advice would be to try a bit of everything at first. Pick a hard science (physics,chem,bio,geo,astro,etc). Pick a soft science (socio,psych,history,etc). Pick an art. Pick a pre-engineering (math,computers). Make a list of things that you are sort of interested and dive right in. Don't be afraid to change as you go.
Also, if you are in no hurry and have the resources, take your time. Nobody says you have to finish college in 4-5 years. Don't expect to be "done" either if you really do enjoy the process of discovering what you like best.
