Every instant of time... is a pinprick of eternity.

Your days are numbered. Use them to throw open the windows of your soul to the sun. If you do not, the sun will soon set, and you with it.

If it is not right do not do it; if it is not true do not say it.

Stop whatever you're doing for a moment and ask yourself: Am I afraid of death because I won't be able to do this anymore?

Which is recorded of Socrates, that he was able both to abstain from, and to enjoy, those things which many are too weak to abstain from, and cannot enjoy without excess. But to be strong enough both to bear the one and to be sober in the other is the mark of a man who has a perfect and invincible soul.

In an expression of true gratitude, sadness is conspicuous only by its absence

Do not act as if you were going to live ten thousand years. Death hangs over you. While you live, while it is in your power, be good.
