A boy or young man who has some serious constructive purpose will endure voluntarily a great deal of boredom if he finds that it is necessary by the way. But constructive purposes do not easily form themselves in a boy's mind if he is living a life of distractions and dissipations, for in that case his thoughts will always be directed towards the next pleasure rather than towards the distant achievement.
