Keep in mind how fast things pass by and are gone - those that are now, and those to come. Existence flows past us like a river; the "what" is in constant flux, the "why" has a thousand variations. Nothing is stable, not even what's right here. The infinity of past and future gapes before us - a chasm whose depths we cannot see.

A man's true delight is to do the things he was made for.

Though you break your heart, men will go on as before.

A man's worth is no greater than his ambitions.

Happiness is no other than soundness and perfection of mind.

Think of what you have rather than of what you lack. Of the things you have, select the best and then reflect how eagerly you would have sought them if you did not have them.

Thou seest how few be the things, the which if a man has at his command his life flows gently on and is divine.
