As soon
Seek roses in December, ice in June;
Hope constancy in wind, or corn in chaff;
Believe a woman or an epitaph,
Or any other thing that's false, before
You trust in critics.
Alas! they had been friends in youth;
But whispering tongues can poison truth,
And constancy lives in realms above;
And life is thorny, and youth is vain,
And to be wroth with one we love
Doth work like madness in the brain.
The secret of success is constancy to purpose.
