Know why you play the game and where you find your satisfaction and joy in it. Most golfers play with clubs that don't fit them, or that no longer suit their games. Graphite shafts and new club designs have revolutionized golf. Active golfers should have their clubs checked for loft, lie, and length, and have them re-gripped every season. Almost any job is easier with the right tools.
Golfers go to extremes.
Some take lesson after lesson, trying to fix the tiniest flaw in their quest for the perfect swing. Success is usually found in a healthy balance of learning from the wisdom and experience of others, while celebrating your unique style and approach to the game. On the day of a big tournament, I often go to the practice green and watch skilled, dedicated golfers practice missing putts. With a small crowd milling about, they quickly hit putt after putt, destroying their rhythm, timing and confidence. In golf, and in life, practice smart.
