Making the complicated awesomely simple, that’s creativity.
There’s a larger chunk this bit comes from as well, where Mingus said “My son’s a painter. All through school his teachers tell him he’s a genius. I tell him to paint me an apple that looks like and apple before he paints me one that doesn’t. Go where you can go, but start from someplace recognizable. Making the simple complicated is commonplace; making the complicated simple, awesomely simple, that’s creativity.”
I just love the bit about the apple.
