Once upon a time, there lived a man named Clarence who had a pet frog named Felix. Clarence lived a modestly comfortable existence on what he earned working at the Wal-Mart, but he always dreamed of being rich. “Felix!” he said one day, hit by sudden inspiration, “We’re going to be rich! I’m going to teach you to fly!”
Felix, of course, was terrified at the prospect. “I can’t fly, you twit! I’m a frog, not a canary!”
Clarence, disappointed at the initial response, told Felix: “That negative attitude of yours could be a real problem. We’re going to remain poor, and it will be your fault.”
So Felix and Clarence began their work on flying.
