Inspiration
While in New Jersey, I also visited the USGA museum. It possesses an outstanding collection of golf memorabilia, including rooms dedicated to Arnold Palmer, Jack Nicklaus, Ben Hogan, Bobby Jones, and Mickey Wright. The Nicklaus room, in particular, stood out for sharing a look into Jack's mindset. Check out these thoughts:
On visualization: "I never hit a shot, not even in practice, without having a picture of it in my mind."
On confidence: "Confidence is the most important single factor in this game, and no matter how great your natural talent, there is only one way to obtain and sustain it: work."
On stress: "The biggest tension-reliever of all in golf is confidence."
On motivation: "What has motivated me is the sheer challenge of the game itself. Of doing something as well as I possibly can for the enjoyment of that effort."
No matter what your sport or activity is, it would be wise to follow the advice this legendary performer. I think you can see how it applies in any context.
