　　There is a beautiful story I heard once about a child playing with a vase(花瓶) his mother had left on the table for a few moments. When the mother turned at the sound of her son crying, she saw that his hand was in the vase and was obviously stuck. She tried to help him and pulled and pulled until the child cried out in pain. But the hand was stuck fast. How would they get it out? The father suggested breaking the vase but it was quite valuable and the child's hand might be cut in the process. Yet he knew that if all else failed, there would be no other alternative. So he said to the boy, "Now, let's make one more try. Open your hand and stretch your fingers out straight, like I'm doing, and then pull!" "But Dad," said the boy, "if I do that, I'll lose my penny!"

　　The boy had had a coin in his hand all the time and was holding it securely in his tight little fist. And he wasn't prepared to open his hand and lose the penny. But once he opened his hand, it came out of the vase easily.

　　I used to hold on to things in my life that I thought were so important to me. Early in my marriage, all I cared about was becoming the best volleyball player in the state of Wisconsin. One year, when Kristi was working shifts at General Motors, I played in 1,400 games, competing four nights a week and 40 out of 52 weekends. My team won over 1,000 games. Success on the volleyball court, but a huge loss in my relationship with my Kristi.

　　When I finally let go, I looked back at what I had done and was ashamed. Not only did I show my wife she wasn't the most important thing to me, but I missed out on a lot of relationship building time. My life is so much richer now that I am not a slave to that drive to be the best player I could be.
