Work helps prevent one from getting old. My work is my life. I cannot think of one without the other. The one who works and is never bored is never old. A person is not old until regrets take the place of hopes and plans. Work and interest in worthwhile things are the best remedy for aging. ... With age your facility of expression and perception diminishes. I have almost nothing left but time. But if I can be of service, I would like to go on living.
Since noise is increasing in all directions, the psychology of silence has taken on a special meaning. We are already so adapted to an abundance of screeching sound that we are surprised when stillness suddenly envelops us. Not that this happens very often. We begin to see that the whole question of our relation to the world, both positive and negative, centers in something like silence. So our service to the world might be simply to keep a place where there is no noise, where people can be silent together.
