I only sell 9. To get one sale I may have had to speak to 10 people. Baseball, and especially last year's home run quest by Mark McGuire and Sammy Sosa is a great example of failure. Both these men swung at the ball and missed it or hit it the wrong way about 100 times more often than they hit it the way they wanted. Seven times out of ten at bats, he walks back to the dugout having been unsuccessful at his job.
Baseball is a game of statistics and so is life.
Thomas Edison is known to have tried to create the electric light bulb more than 1000 different ways. Every failure moved him toward to his goal. Thomas Edison, Sammy Sosa, Mark McGuire, all had one thing in common. They looked at their results as feedback which helped them adjust their actions and move toward greater and greater chances for success. They learned from their mistakes.
