To live in the right way is a very difficult art, and unless one begins to learn it when quite young and to make an effort, one never knows it very well. Simply the art of keeping one’s body in good health, one’s mind quiet and goodwill in one’s heart— things which are indispensable in order to live decently—I don’t say in comfort, I don’t say remarkably, I only say decently.Well, I don’t think there are many who take care to teach this to their children.
