Let no one be slow to seek wisdom when he is young nor weary in the search of it when he has grown old. For no age is too early or too late for the health of the soul.
I was not, I was, I am not, I care not. It's a Latin saying found on Roman grave markers. It means I wasn't bothered about not existing before I existed and I'm not bothered about not existing now that I don't exist.
One who understands the limits of the good life knows that what eliminates the pains brought on by need and what makes the whole of life perfect is easily obtained, so that there is no need for enterprises that entail the struggle for success.
