Leadership consists not in degrees of technique but in traits of character; it requires moral rather than athletic or intellectual effort, and it imposes on both leader and follower alike the burdens of self-restraint. Lewis H Lapham
The best executive is the one who has sense enough to pick good men to do what he wants done, and self-restraint enough to keep from meddling with them while they do it. Theodore Roosevelt
Such power there is in clear-eyed self-restraint. James Russell Lowell
Restraint never ruins one’s health. What ruins it is not restraint but outward suppression. A really self-restrained person grows every day from strength to strength and from peace to more peace. The very first step in self-restraint is the restraint of thoughts. Mahatma Gandhi
