Reason with people. Luck is a four letter word people use when they're describing the success of someone of whom they are jealous. The mind is not a vessel to be filled but a fire to be kindled. We deceive ourselves. The mind leads, the emotions follow.
Contentment leads to mediocrity which in turn leads to disaster.
A man would do nothing, if he waited until he could do it so well that no one could find fault. There is no heavier burden than having great potential. You have to do it a lot to get good at it. If it's not done by you it will be by someone else. The greater my capacity and willingness to please my fellow man, the more I can earn.
