..it is helpful to think of your life not in terms of work but in terms of music—particularly a symphony. A symphony, traditionally, has four parts to it—four movements, as they’re called. So does Life. There is the first movement, infancy; then the second movement, the time of learning; the long third movement follows, the time of working; and finally, this fourth movement, traditionally called “retirement,†though now that is an increasingly complex concept. It is much better to think of it as the Fourth Movement, a triumphant, powerful ending to the symphony of our life here on earth.
