Why golf is difficult.

The ball is a mere 1.68 inches in diameter. Any impact above the equator -- the horizontal midline -- of the ball is a miss, so the whole target is 0.84 inches. Subtract about 1/8 inch for the little depression in the fairway that the ball has nestled into, and we're down to 0.58 inches. Another eight of an inch for the grass, and we're at 0.42 inches.

Even on an easy swing with a wedge, the clubhead is traveling at about 50 mph. Imagine trying to drive a car going 50 mph through an opening with 0.22 inches on each side. Not an exact analogy, but that should give you an idea.

Damn tough game.
