Mine is a bit along the line of MBC's.

I have a music theory/composition degree. I went to school on a vocal scholarship. Would have rather it been basketball, but there are about a million 6' white boys better than I am. Wasn't as gifted there as I would have liked, but I coach HS ball now, so it's OK. Anyway....

I don't know if this is a regret about something I should have tried long ago or something I'd like to do now.

I'd go the vocal performance route now. I went to school with people that now perform on broadway or sing in NY City opera, and I miss the performance. I paid my living expenses in college doing musical theater and as a singing waiter, and I miss that. It kills me when I see people performing now in a few traveling shows I've seen here in Phoenix when (this is probably pretty arrogant) I know I was better than they were at one point. I'd love to have the chance to perform on a big stage again. Loved it in HS, loved it in college, and I am pretty sure I'd love it now.

I just didn't have the desire then to do the work for vocal performance and loved the mathematical aspects of theory and composition. Counterpoint was so much more fun than private voice lessons. But now.....I don't compose anything and couldn't spell a French 6th chord anymore (much less respell it to change keys), so I almost feel like I wasted my abilities and 4 years of school (with the exception of the degree). But performing.....miss it. Wish I could do it again.

I would love to go back to school to finish up my Art History studies and teach or curate. I miss the art world and I miss academia (even with all of the writing involved). But, that's a looooong haul and I have much more income potential with marketing or RE. So, I am wimping out.

I live with no regrets, I'll die with no regrets
