"Building alibis with which to explain away failure is a national pastime. The habit is as old as the human race, and is fatal to success! Why do people cling to their pet alibis? The answer is obvious. They defend their alibis because THEY CREATE them! A man's alibi is the child of his own imagination. It is human nature to defend one's own brain-child...Building alibis is a deeply rooted habit. Habits are difficult to break, especially when they provide justification for something we do. Plato had this truth in mind when he said, The first and best victory is to conquer self. To be conquered by self is, of all things, the most shameful and vile. ...In parting, I would remind you that "Life is a checkerboard, and the player opposite you is time. If you hesitate before moving, or neglect to move promptly, your men will be wiped off the board by time. You are playing against a partner who will not tolerate indecision! p. 173"
