a golfer envisions and attempts to anticipate every shot as if it were going to be a hole-in-one, even though most of them will not be... but in the process, achieves a better result than if s/he anticipated performing an average shot.

Suppose there is a lake between the tee and the hole, too big for the golfer to hit the ball all the way across. Should he envision/anticipate a hole in one, and waste his first stroke hitting the ball into the water, or should he acknowledge that this hole will take multiple strokes, and hit the ball around the lake?
