Live each day as if it be your last.
If any man has done wrong, the harm is his own. But perhaps he has not done wrong.
The memory of everything is very soon overwhelmed in time.
To the wise, life is a problem; to the fool, a solution.
Search men's governing principles, and consider the wise, what they shun and what they cleave to.
Think of yourself as dead. You have lived your life. Now, take what's left and live it properly. What doesn't transmit light creates its own darkness.
