It is of capital importance that you emphasize what is the basis for holiness and the foundation of goodness. I mean to talk about the virtue of which Jesus presents himself explicitly as the model: humility (cf. Mt 11,29). Inner humility; more inner than outward. Recognize who you truly are: a nothing, something quite miserable, weak, full of defects, capable of turning good into bad, to let go the good for the bad, to attribute to yourself the good, and to justify yourself in doing bad, and for love of evil, to despise the One who is the Supreme Good.
Never go to bed before having first examined your conscience to consider how you spent your day. Turn all your thoughts towards the Lord and consecrate your person to him as well as all the Christians. Then offer to his glory the sleep you will get, without ever forgetting your guardian angel, who is always at your side.
