The greatest man is he who chooses right with the most invincible resolution; who resists to sorest temptation from within and without; who bears the heaviest burdens cheerfully; who is calmest in storms, and most fearless under menaces and frowns; whose reliance on truth, on virtue, and on God is most unfaltering.
Seneca the YoungerIt is easier to exclude harmful passions than to rule them, and to deny them admittance than to control them after they have been admitted.
Seneca the Younger
