Attempt the end, and never stand to doubt;
Nothing’s so hard but search will find it out.

The couplet urges resolute action: fix your aim (“Attempt the end”) and do not hesitate in self-doubt. The second line generalizes the lesson into a proverb—no problem is so difficult that sustained investigation and effort cannot uncover a solution. “Search” implies both practical striving and intellectual inquiry, so the advice applies to moral resolve, learning, and craft alike. The rhyme and balanced syntax reinforce the message’s certainty, turning perseverance into a kind of ethical posture. In Herrick’s idiom, the lines also carry a gentle rebuke to timidity: difficulty is not an excuse to stop, because discovery is the reward of continued seeking.
