I recently read an article about when it comes to the game of golf, you can teach an old dog new tricks. Really, it all comes down to your mental game and whether or not you believe you can learn something new.
My motto is that the only dog you can't teach a new trick to is a dead dog. So as long as you're breathing, you can learn a new swing. As we get older, we'll never be able to match the distance we once had as younger golfers, but we can become more efficient players by utilizing the right swing in combination with proper equipment.
One of the biggest things to remember as you age is that your short game has to become the best part of your game. This is where you will make up the difference for your loss in distance.
The key is to open your mind and change your attitude when it comes to golf. The PPGS can lead to success, as long as you're willing to try.
Keep it vertical!
