"Were you to live three thousand years, or even thirty thousand, remember that the sole life which a man can lose is that which he is living at the moment; and furthermore, that he can have no other life except the one he loses…This means that the longest life and the shortest amount to the same thing. For the passing minute is every man's equal possession, but what has once gone by is not ours."
"Your time has a limit set to it. Use it, then, to advance your enlightenment; or it will be gone, and never in your power again."
"Take it that you have died today, and your life's story is ended; and henceforward regard what future time may be given you as an uncovenanted surplus, and live it out in harmony with nature."
