“A man of sense is never discouraged by difficulties; he redoubles his industry and his diligence, he perseveres, and infallibly prevails at last.”

What this quote means

Lord Chesterfield contrasts the reaction of the wise and the fool in the face of difficulties. The sensible man does not let himself be defeated; he intensifies his efforts. This quote is a hymn to active perseverance: instead of enduring, one redoubles ardor. It suggests that victory is inevitable for those who refuse to give up, a conviction that can sustain us in times of trial.
