The 100th Idiot

"100 idiots make idiotic plans, and carry them out. All but one justly fail. The hundredth idiot whose plans succeeded through pure luck, is immediately convinced he's a genius."

Iain M. Banks, Matter

I'll be using the term "100th Idiot" a lot, I expect, best you know where it comes from. And reading Iain Banks books is worthwhile in itself.
