Charles de Gaulle Quote
Nothing more enhances authority than silence. It is the crowning virtue of the strong, the refuge of the weak, the modesty of the proud, the pride of the humble, the prudence of the wise, and the sense of fools. To speak is to... dissipate one's strength; whereas what action demands is concentration. Silence is a necessary preliminary to the ordering of one's thoughts.
