They who lack talent expect things to happen without effort. They ascribe failure to a lack of inspiration or ability, or to misfortune, rather than to insufficient application. At the core of every true talent there is an awareness of the difficulties inherent in any achievement, and the confidence that by persistence and patience something worthwhile will be realized. Thus talent is a species of vigor.
If you have tried to do something and failed, you are vastly better off than if you had tried to do nothing and succeeded. You must never regret what might have been. The past that did not happen is as hidden from us as the future we cannot see.
There is no failure for the man who realizes his power, who never knows when he is beaten; there is no failure for the determined endeavor; the unconquerable will. There is no failure for the man who gets up every time he falls, who rebounds like a rubber ball, who persists when everyone else gives up, who pushes on when everyone else turns back.
