From Robert Redford's customer letter on Page 2 of the Spring 2010 Sundance Catalog:
Spring. I love Spring. Not only because it springs eternal in the human breast but because it provides a stretch of time to just appreciate the natural beauty of seasons.
Sorry, Bob. Spring doesn't spring eternal. Hope does. Hope. Rhymes with Pope.
Hope springs eternal in the human breast;
Man never is, but always to be blest:
The soul uneasy and confin'd from home,
Rests and expatiates in a life to come.
—Alexander Pope (1688-1744), "Essay on Man," Epistle I.
