“Atta boy, Jack!” he’d say. This compliment, short but sincere, was his reward. Then he’d say to himself: If I can just walk down the street to the gym, I’ll enjoy a chat with the staff there. Once on the treadmill, Jack started by walking for just two minutes, rewarding himself with praise and encouragement. Minute by minute, and small reward by small reward, Jack slowly worked himself into physical fitness. By the time I met him, he was in his seventies and had won the Mr. World bodybuilding contest for his age division!
