This might reflect my tired, semi-depressed, mellow mood, but I would prefer a relaxed life. (Maybe I am bipolar...) Primarily, be a recognized musician of a successful band. As someone with Asperger's, try and encourage and inspire other Aspies growing up, kind of like how both Craig Nicholls and Heather Kuzmich are relatively successful with it.
Ala John Frusciante, I'd like a relaxed schedule - I hope eventually to incorporate stuff like Yoga in my life, quasi-spiritual stuff. Have the freedom, to live a peaceful life, being able to live alone, and be able to easily just work on music all day. Have a few nice contacts with others, but mostly be able to stay in solitude and be happy with it. I'd tolerate a small job as well.
On the other side, when I'm not feeling all "peaceful and relaxed", another reason I'd love to put out music and be successful, is the ability to travel around the world. Sometimes I have wanderlust. Doesn't really help when I've pretty much been living here all my life. It makes me crazy when I hear one of the foreign language classes at my school took a trip to Germany or somewhere. I want to travel around the world so freaking bad. Tours everywhere. Sightseeing. Finally check out Europe, Japan, and many other countries.
In addition, to fill my ADHD fix, being able to go OMGWTFBBQHYPERACTIVESPAZRAWR on stage every day during the tours. Heck yes.
Being a bit of an activist in some ways would be nice, too.
