Just as nature takes every obstacle, every impediment, and works around it--turns it to its purposes, incorporates it into itself, so, too, a rational being can turn each setback into raw material and use it to achieve its goal.

In the end, what would you gain from everlasting remembrance? Absolutely nothing. So what is left worth living for? This alone: justice in thought, goodness in action, speech that cannot deceive, and a disposition glad of whatever comes, welcoming it as necessary, as familiar, as flowing from the same source and fountain as yourself.

Nowhere can man find a quieter or more untroubled retreat than in his own soul.

If you do everything as if it were the last thing you were doing in your life, and stop being aimless, stop letting your emotions override what your mind tells you, stop being hypocritical, self-centered, irritable.

Look well into thyself; there is a source of strength which will always spring up if thou wilt always look.

Remember that man lives only in the present, in this fleeting instant; all the rest of his life is either past and gone, or not yet revealed.

Reflect often upon the rapidity with which all existing things, or things coming into existence, sweep past us and are carried away.
