Horace Quote

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.
