Forbearance and self-control smooth the road of life, and open many ways which would otherwise remain closed.

And so does self-respect: for as men respect themselves, so will they usually respect the personality of others.
It is the same in politics as in business.

Success in that sphere of life is achieved less by talent than by temper, less by genius than by character.

If a man have not self-control, he will lack patience, be wanting in tact, and have neither the power of governing himself nor of managing others.

When the quality most needed in a Prime Minister was the subject of conversation in the presence of Mr.Pitt, one of the speakers said it was "Eloquence;" another said it was "Knowledge;" and a third said it was "Toil," "No," said Pitt, "it is Patience!" And patience means self-control, a quality in which he himself was superb.
His friend George Rose has said of him that he never once saw Pitt out of temper.
