Disdain things you cannot have: Ignoring them is the best revenge: By acknowledging a petty problem you give it existence and credibility. The more attention you pay an enemy, the stronger you make him; and a small mistake is often made worse and more visible when you try to fix it. It is sometimes best to leave things alone. If there is something you want but cannot have, show contempt for it. The less interest you reveal, the more superior you seem.
There is a Chinese Proverb that comes to mind while pondering this rule; “In the struggle between the stone and the water, in time, the water wins.” It is a virtue to have patience and it does take time, effort, and dedication to the practice of patience.
