Music/language/logic(they're all different sides of the same triangle, or some other polygon should more connections be discovered), and fundamental knowledge of the general principles by which our world is governed and our society is panning out.
Also human tragedies/struggles/irrationalities interest me greatly for that's what shaped our history just as much as language and logic have.
I'm already a musician, getting more accomplished by the month, but I want something more. Not that there's any real goal in being a musician other than being able to support yourself with it, and possibly leaving behind something truly remarkable and impactful, anything else is gravy.
I'd also want to pursue some form of advanced scientific study, whether theoretical or applied.
I'm interested in physics, good at math, have some background in biology and chemistry. I have no skill in the technologies, which I'd like to change.
Overall I'd have to say that learning is my passion second only to creating.
