Too many people fear failure. Some of us let it keep us from trying new things, telling ourselves we' d be no good at it. Some limit our goals to only what we feel absolutely sure we can accomplish. Others among us try something once and when it doesn't work out, we decide that course is not for us.That' s unfortunate because, according to many top scientists, failure is nothing to fear. Not only is it inevitable, they say, it is even an indispensable ally. "In the research lab," says John Polanyi, the Nobel prize-winning chemist," failure is a good thing. If everything you try is very successful, it means you' re playing it safe; you' re not out on the edge. Failure means that you' re learning. To ask a scientist whether he has experienced failure is like asking an artist whether he has ever made a sketch. The answer is, ' a million times. ' That is the price of success. "
Failure is not the opposite of success. It' s more like an ingredient. In Hollywood, thousands of ideas for new TV shows are pitched each year, but only a select few get to the screen, let alone survive their first season. In real life, misses outnumber hits whenever people try something new.Nina Spencer, a motivational speaker and author of Getting Passion out of Your Profession, likes to remind audiences that whenever we try a new skill, we go through four stages. "There' s the point when you don' t know about the skill, and because you don' t know about it, you' re no good at it. Eventually, you come to know about the skill, but you' re incompetent to perform it.
Then, as long as you think carefully and go slowly, you can do it. Eventually, it becomes so practiced, it' s easy. " The secret is not to give up at stage two.
In short, the seeds of success almost always flourish best in the well-turned soil of failure. As Charles Kettering, inventor of the modem electric ignition system for cars and the holder of nearly 200 patents, once said, "failures, repeated failures, are finger-posts on the road to achievements-- one fails forward towards success. "
