From his book, Wooden: A Lifetime of Observations and Reflections On and Off the Court (1997) - - from a section entitled Learn Forever, Die Tomorrow:
Early on I came to believe that you should learn as if you were going to live forever, and live as if you were going to die tomorrow. What does this mean? In the simplest way, I would explain it like this.
Always be learning, acquiring knowledge, and seeking wisdom with a sense that you are immortal and that you will need much knowledge and wisdom for that long journey ahead. Know that when you are through learning, you are through.
But I want to live the life as if I were going to die tomorrow: with relish, immediacy, and the right priorities. I also will not waste even a minute.
