Here’s a Jack Nicklaus story about having a positive mind.
Apparently Nicklaus was speaking to a group and mentioned that he never missed a putt on the final green that made him lose a tournament. An audience member raised his hand and said, “Yes, you did. It was at [this] tournament.” Nicklaus replied that he hadn’t missed that putt, and the questioner said, “Yes you did. I even have it on tape.” Nicklaus replied again, “No, I didn’t miss that putt.”
Well, Nicklaus had missed the putt, but he had also erased the miss from his mind. He refused to make that putt part of his history. That his memory no longer agreed with established facts was of no concern to him. He wanted to know that when he has to make a putt, he will, because his mind contains no evidence to the contrary.
When you come home from the course, remember your good shots clearly. The ones that didn’t work out so well, erase them. They never happened.
Put plus in your mind, don’t let minus in, and you’ll become the golfer you want to be.
