I asked the question this morning, and this evening I found, maybe not the answer, but certainly an answer in John Dryden (1631-1700), translating Horace:
Happy The Man
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 of fate, are mine.
Not heaven itself upon the past has power,
But what has been, has been, and I have had my hour.
It is the old adage: CARPE DIEM - Seize the Day
