I get anxious about a lot of things, that's the trouble. I get anxious about everything. I just can't stop thinking about things all the time. And here's the really destructive part - it's always retrospective. I waste time thinking of what I should have said or done.
But yeah, I played bass guitar in high school and in college and then I actually fractured my thumb, so my bass career went bye-bye.
Conflict and character are the heart of good fiction, and good mystery has both of those in spades.
