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 YoungerWe should every night call ourselves to an account: What infirmity have I mastered today? What passions opposed? What temptation resisted? What virtue acquired? Our vices will abate of themselves if they be brought every day to the shrift.
Seneca the YoungerWe are so vain as to set the highest value upon those things to which nature has assigned the lowest place. What can be more coarse and rude in the mind than the precious metals, or more slavish and dirty than the people that dig and work them? And yet they defile our minds more than our bodies, and make the possessor fouler than the artificer of them. Rich men, in fine, are only the greater slaves.
