I am extremely jealous of people who have cool or unique side talents. Take my friend John Collins. Not only does he have a regular day job he is one of the best paper airplane designers in the country having written a few books on the subject. He recently held court with kids and adults at the Exploratorium.
He turned what he did in the 4th grade into a profitable and fun hobby. All I got out of the fourth grade was a binder filled with stickers.
His designs are amazing, even if some are too darn tough to fold.
