Why worry about things you can't control when you can keep yourself busy controlling the things that depend on you?
John C. MaxwellA man must be big enough to admit his mistakes, smart enough to profit from them, and strong enough to correct them. This sequence is something that all achievers have in common. They do not see a mistake is as their failure; rather it is simply a learning experience. Achievers view a mistake as an opportunity to do something over again and do it right the second time. A mistake is simply the price they pay to achieve success.
