" Several years ago, I was playing basketball with our son Jonathan. We’ve played one-on-one for years. For the first time, he beat me, fair and square, 15--14. I gave him a high five. Then I told him he was grounded!
During the game at one point Jonathan dribbled around me and went up for a shot. I came out of nowhere, timed it just right, and blocked his shot. I swatted the ball away and it went flying into the bushes.
I felt like an NBA star. A couple days later, we went to the gym to play with some friends. Jonathan said, “Dad, tell everybody what happened the other night.”
I said, “Oh, yeah, Jonathan went up for this shot, and I must have been this high in the air and I blocked it, and it was something else.”
He said, “No, Dad, I meant tell them how I beat you for the first time!”
What’s funny is, I didn’t remember my defeat, I remembered my victory The first thing that came to my mind wasn’t that I lost the game to him, but the fact that I did something good. It’s because I’ve trained my mind to remember the right things.
For many people it’s just the opposite. They won the game, but they remember all the mistakes they made. They never feel good about themselves. They’re always focused on something they didn’t do good enough.
It’s all in how you train your mind. It depends on what channel you’re watching. Don’t make the mistake of remembering what you should forget, whether it’s your hurts, your disappointments, or your failures. Don’t forget what you should remember--your victories, your successes, and the hard times you overcame. "
