I used to practice the piano in my grandma's apartment in the basement of our house. I believed that if I played a wrong note, a lion would burst out of the closet door and attack me. But when I did play a wrong note and nothing horrible happened, I figured it would take two wrong notes. And after two wrong notes, it would take three, etc.
