When he was 9 years old, he saw his first magic act, and knew immediately what he wanted to do. From that moment on, he studied magic obsessively and spent every spare minute practising every detail of every move.
He never performed -- never did a single trick in front of another person. He just kept practising, until he could do them all flawlessly.
Now he goes to magic shows, and he always volunteers. That's when he uses his hard-earned skills, and watches with silent delight as the magician pulls out the wrong card or fails to make a coin reappear.
