I notice a repeat of this kind of thinking on the golf course. Many golfers focus on their bad shots. Ask them how their game went and they will usually answer, "I missed some close putts," or, "I just couldn't find the fairway." What about the other 70 or 80 shots? Is it human to forget about the good and remember the bad? And does it affect your game?
What happens when you focus on the last putt you missed is that you carry it onto the next hole. Remember golf is one round, one hole, one shot. And while you are still carrying the visual of the bad shot, it's almost impossible to follow it up with a good one.
If, in fact, gratitude is the prayer of appropriation, then I believe it's important to remember and be grateful for the putt you did sink, or the one chip that landed two feet from the hole. After all, if you focus on what you can do, chances are you have a better chance of repeating it.
It's in your best interest to stay positive and grateful, in life and in golf. Even if your game is not working on a particular day, you can be grateful that you are out in the fresh air, enjoying the company of friends, in a beautiful place. Try focusing more on the good, on what you have and what you can do and your life will get better and better. Try it - I think you'll like it!
