A man who fails well is greater than one who succeeds badly.

Who is willing to be satisfied with a job that expresses all his limitations? He will accept such work only as a 'means of livelihood' while he waits to discover his 'true vocation'. The world is full of unsuccessful businessmen who still secretly believe they were meant to be artists or writers or actors in the movies.

You can't go home again

If a man has talent and can't use it, he's failed. If he uses only half of it, he has partly failed. If he uses the whole of it, he has succeeded, and won a satisfaction and triumph few men ever know.

Success isn't permanent and failure isn't fatal.

Growth comes in the aftermath of failure, not wild success.
