Green Bing.

Happy the man, and happy he alone,
   He who can call today his own:
   He who, secure within, can say,
Tomorrow do thy worst, for I have lived today.
Be fair or foul or rain or shine
The joys I have possessed, in spite or fate, are mine.
Not Heaven itself upon the past has power,
But what has been, has been, and I have had my hour.

"Happy the Man" by Horace, from Odes, Book III, xxix. Translation by John Dryden. From the Writer's Almanac. (buy now)
