A)The Mishnah Berurah brings as a Halacha that one should learn Mussar every day. (suggestion five minutes a day from a sefer that speaks to you).

B)The Rama suggests that when one goes to sleep he should have in mind, in front of whom he is lying, so that when he’ll wake up it will be with Hashem in mind, and this will make his day one of constant awareness of Hashem’s existence.
