My unfulfilled career pursuit is Stand Up Comedy. Being an extrovert, I love being in front of a crowd. Sometimes when I teach (I'm a college professor), my students laugh throughout the whole class session as I try to make the information more fun.
I may or may not ever step up and try an amateur night at the comedy club. Again, being an extrovert, we're not very good with rejection and want everybody to like us, so if I bombed on stage, it would be hard on me.
