Why are so many people so afraid of failure? Quite simple because no one tells us how to fail so that failure becomes an experience that will lead to growth. We forget that failure is part of the human condition and that every person has the right to fail.

Most parents work hard at either preventing failure or protecting their children from the knowledge that they have failed. One way is to lower standards. A mother describes her child’s hastily made table as “Perfect!” even though it doesn’t stand still. Another way is to shift(转移)blame. If John fails science, his teacher is unfair or stupid.

The trouble with failure prevention is that they leave a child unequipped for life in the real world. The young need to learn that no one can be best at everything, no one can win all the time and that it’s possible to enjoy a game even when you don’t win. A child who’s not invited to a birthday party, who doesn’t make the honour roll on the baseball team, feels terrible, of course. But parents should not offer a quick comfort, prize or say “It doesn’t matter.” because it does. The young should be allowed to experience disappointment and be helped to master it.

Failure is never pleasurable. It hurts grownups and children alike. But it can make a positive contribution to your life once you learn to use it. Step one is to ask “Why did it fail? Don’t blame someone else. Ask yourself what you did wrong, how you can improve. If someone else can help, don’t be shy about inquiring. Success, which encourages repetition of old behaviour, is not nearly as good a teacher as failure. You can learn from a bad party how to give a good one, from an ill-chosen first house what to look for in a second. Even a failure that seems definitive can cause fresh thinking, a change of direction. After twelve years of studying ballet, a friend of mine applied for a professional company. She asked. That ballet master shook his head. “You will never be a dancer,” he said,” you haven’t the body for it.”

In such cases, the way to use failure is to take stock bravely asking “What have I left? What else can I do?” My friend put away her shoes and moved into dance treatment center, a field where she’s both able and useful. Failure frees one to take risks because there’s less to lose. Often there is recovery of energy — a way to find new possibilities.
