True happiness is to enjoy the present, without anxious dependence upon the future, not to amuse ourselves with either hopes or fears but to rest satisfied with what we have, which is sufficient, for he that is so wants nothing. The greatest blessings of mankind are within us and within our reach. A wise man is content with his lot, whatever it may be, without wishing for what he has not.
Seneca the YoungerIn the meantime, cling tooth and nail to the following rule: not to give in to adversity, not to trust prosperity, and always take full note of fortune's habit of behaving just as she pleases.
Seneca the YoungerThere is no benefit so large that malignity will not lessen it; none so narrow that a good interpretation will not enlarge it.
