No one can lead a happy life, or even one that is bearable, without the pursuit of wisdom, and that the perfection of wisdom is what makes the happy life, although even the beginnings of wisdom make life bearable. Yet this conviction, clear as it is, needs to be strengthened and given deeper roots through daily reflection; making noble resolutions is not a important as keeping the resolutions you have made already.
Seneca the YoungerThe 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 Younger
