"Get a shovel, go outside, dig up the neighbor's backyard. You will find El Dorado there."
I love in this one book that we were read in elementary school, the main character developed telekinetic powers over time through concentration exercises. He then went to a casino, first hand he hit his 20 because he knew the next card was an ace. He then realized that was rather stupid as he will get noticed very quickly playing like that. He walked up to the roulette table instead, and bet a bunch on one number, which of course was the next one to be rolled.
For this abuse of his power, he died of a heart attack that very night!
