The best of all things is to learn. Money can be lost or stolen, health and strength may fail, but what you have committed to your mind is yours forever.
Louis L'AmourThe only power source a book needs is you. If you have to leave for a few minutes you have not lost the story. It is waiting for you when you return. You can pick up a book and resume reading at any time, after a few minutes, a few days, even a few years. A television picture or a movie might be lost forever, but your book is waiting.
