Marcus Aurelius, Meditations 6.6

Begin the morning by saying to thyself, I shall meet with the busy-body, the ungrateful, arrogant, deceitful, envious, unsocial.

Take away thy opinion, and then there is taken away the complaint, 'I have been harmed.' Take away the complaint, and the harm is taken away.

At dawn, when you have trouble getting out of bed, tell yourself: 'I have to go to work — as a human being.'
