Two things that you might want to consider hanging on your wall and living by to improve the happiness of your family:
1. D&C 121:
39 We have learned by sad experience that it is the nature and disposition of almost all men, as soon as they get a little authority, as they suppose, they will immediately begin to exercise unrighteous dominion.
40 Hence many are called, but few are chosen.
41 No power or influence can or ought to be maintained by virtue of the priesthood (or manhood or womanhood or motherhood), only by persuasion, by long-suffering, by gentleness and meekness, and by love unfeigned;
42 By kindness, and pure knowledge, which shall greatly enlarge the soul without hypocrisy, and without guile—
43 Reproving betimes with sharpness, when moved upon by the Holy Ghost; and then showing forth afterwards an increase of love toward him whom thou hast reproved, lest he esteem thee to be his enemy;
44 That he may know that thy faithfulness is stronger than the cords of death.
2. Matthew 6 (with one little addition from me):
14 For if ye forgive men their trespasses, your heavenly Father will also forgive you:
15 But if ye forgive not men their trespasses, neither will your Father forgive your trespasses.
I must forgive you to be forgiven, but that does not mean that I get to demand that you forgive me.
