"Shun then, Achilles, shun the faults of such,
"Who still propose too little, or too much.
"Stretch not your hopes too far, nor yet despair,
"But above all, of indolence beware.
"Attend to what you do, or life will seem
"But a mere vision, or fantastick dream,
"Pass'd in ideas of delight, at best:
"While real pleasure's lost in doubtful rest.
"In short, learn when, and how to bear; in vain
"He pleasure seeks, who is afraid of pain;
"Pleasure's a serious thing, and cheaply bought
"By labour, patience, management, and thought.
