"We cannot choose how many years we will live, but we can choose how much life those years will have. We cannot control the beauty of our face, but we can control the expression on it. We cannot control life's difficult moments but we can choose to make life less difficult. We cannot control the negative atmosphere of the world, but we can control the atmosphere of our minds. Too often we try to choose and control things we cannot. Too seldom we choose to control what we can … our attitude." John Maxwell (Developing the Leader Within You)
