It is in your power to withdraw yourself whenever you desire. Perfect tranquility within consists in the good ordering of the mind, the realm of your own.

If unwilling to rise in the morning, say to thyself, 'I awake to do the work of a man.'

The longest-lived and the shortest-lived man, when they come to die, lose one and the same thing.

...the infallible man does not exist.
