"'T is not in mortals to command success:"[659]But do you more, Sempronius—don't deserve it,

And take my word, you won't have any less.

Be wary, watch the time, and always serve it;

Give gently way, when there's too great a press;

And for your conscience, only learn to nerve it;

For, like a racer, or a boxer training,

'T will make, if proved, vast efforts without paining.
