Do not speak while you feel the impulse of anger, for you will be almost certain to say too much, to say more than your cooler judgment will approve, and to speak in a way that you will regret.

Be silent until the "sweet by and by," when you will be calm, rested, and self-controlled.
But self-respect must be accompanied by self-conquest, or our strong feelings may prove but runaway horses.

He who would command others must first learn to obey, and he who would command his own powers must learn to be submissive to the still small voice within.

Discipline the passions, curb pride and impatience, restrain all hasty impulses.

Deny yourself the gratification of any desire not sanctioned by reason.
