"In fact, life is our greatest teacher. Whatever we are doing can be instructive, whether we are at the office, or talking to our spouse, or driving a car on the freeway. If we are present to our experiences, the impressions of our activities will be fresh and alive, and we will always learn something new from them. But if we are not present, every moment will be like every other, and nothing of the preciousness of life will touch us."
