Theodore Sturgeon was a science fiction writer until his death in 1985. He is known for what we now call Sturgeon's Law, in effect, "90 percent of everything is crud."
True, 90 percent of science fiction writing is crud, but so are 90 percent of television shows, electrician output, photocopy machine repairs, carpet colors, and--certainly--standup comedy.
The ten percent are special. They shine. We should all strive to be in the ten percent.
