“Procrastination robs the world of countless treasures.”

“No thief, however skillful, can rob one of knowledge, and that is why knowledge is the best and safest treasure to acquire.”

“With age, gone are the forevers of youth. Gone is the willingness to procrastinate, delay, to play the waiting game. Now each day is a treasure beyond compare . . . because there are so few such diadems left.”

“Stop searching the world for treasure, the real treasure is in yourself.”

“If once a man indulges himself in murder, very soon he comes to think little of robbing; and from robbing he comes next to drinking and Sabbath-breaking, and from that to incivility and procrastination. Once begun upon this downward path, you never know where you are to stop. Many a man has dated his ruin from some murder or other that perhaps he thought little of at the time.”

“Industrial tourism is a threat to the national parks. But the chief victims of the system are the motorized tourists. They are being robbed and robbing themselves. So long as they are unwilling to crawl out of their cars they will not discover the treasures of the national parks and will never escape the stress and turmoil of the urban-suburban complexes which they had hoped, presumably, to leave behind for a while.”
