I always make mistakes and take calculated risks on the tennis court. When my focus or concentration wavers, I unintentionally miss-hit the ball or fail to get in position for a solid return. Sometimes I'll rush the net when I shouldn't, or hit the ball long when trying to land a baseline corner.
What I should do is quickly re-focus my attention or reconsider the risks I take. Instead, I often yell at myself. Occasionally I'll slam the ball against the fence or toss my racket. Does this self-critical "punishment" ever help? Of course not. It only makes matters worse. The same is true for your golf game, and for meeting the continuous challenge of preventing injuries in the workplace.
