When you want to cheer yourself up, think of the good qualities of those you live with.
For instance, the energy of one, the modesty of another, the generosity of a third, and so on.
For nothing gives us as much pleasure as seeing the examples of the virtues presented in abundance by those who live among us.
Therefore keep them always near at hand.
Marcus Aurelius Meditations the spiritual teaching of Marcus Aurelius, pp.112-113
