Seneca

“ You understand without my mentioning it that an unbroken calm and freedom ensue, when we have driven away all those things which either excite us or alarm us: for in the place of sensual pleasures and and those slight perishable matters which are connected with the basest crimes, we thus gain an immense, unchangeable, equable joy, together with peace, calmness and greatness of mind, and kindliness: for all savageness is a sign of weakness. ”

“ It is not far distant from us; it can be discovered: all that is necessary is to know whither to stretch out your hand: but, as it is, we behave as though we were in the dark, and reach out beyond what is nearest to us, striking as we do so against the very things that we want. ”

“ A happy life, therefore, is one which is in accordance with its own nature, and cannot be brought about unless in the first place the mind be sound and remain so without interruption, and next, be bold and vigorous, enduring all things with most admirable courage, suited to the times in which it lives, careful of the body and its appurtenances, yet not troublesomely careful. ”
