True joy is a serene and sober motion; and they are miserably out so that take laughing for rejoicing; the seat of it is within, and there is no cheerfulness like the resolutions of a brave mind.
Seneca the YoungerNo 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 Younger
