Great story, Alberto. I'll check-out the book. Thanks!!!

I learned a similar lesson from my father, although it was an "indirect" teaching. After dinner mostly in the winter my dad and I would play ping-pong in the basement. He would do things that made me furious and I would blow-up and lose game after game. Until, I thought, 'This is supposed to be fun'.

I chose to let go of my anger when I played. After that I won every game. My father stopped playing with me. "He didn't feel like it," he said.

Later I asked him why he stopped playing with me. He said this: "I saw from the beginning that you were a better player than me. I used psychological tactics - like provoking you to get angry so I could win. When you stopped getting angry you became a much better player and my tricks could no longer worked on you."
