The poets aim is either to profit or to please, or to blend in one the delightful and the useful. Whatever the lesson you would convey, be brief, that your hearers may catch quickly what is said and faithfully retain it. Every superfluous word is spilled from the too-full memory.
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.
