“Each part of your life—today’s behavior, tomorrow’s behavior, next week’s behavior, next month’s behavior—can be examined in the context of the whole, of what really matters most to you. By keeping that end clearly in mind, you can make certain that whatever you do on any particular day does not violate the criteria you have defined as supremely important, and that each day of your life contributes in a meaningful way to the vision you have of your life as a whole.”
