Track the changes and see just how much you can improve by focussing on something other than your swing or the clubs your not too happy with. Your enjoyment of the game will heighten. If you already do this to some extent, increase the detail of your plan. Begin using your mind's eye to see the ball travelling from tee to green on every hole. Bring this imagery to your pre-shot routine so the 'the sight' of your ball travelling to its intended target is the last thing on your mind before you attempt a shot.
Imagery is an extremely powerful tool.
Certainly we are not all professional athletes or rely on golf for our livelihood. We all, however, would like to improve our scores and lower our handicaps. Using our mental abilities, we can do this without adjusting a single component of our swing, purchasing new clubs or even a series of lessons from a Golf Professional.
