These are all good ideas, and there are more. The quote included by Howard W. Hunter gives more ideas:
“This Christmas, ‘Mend a quarrel. Seek out a forgotten friend. Dismiss suspicion and replace it with trust. Write a letter. Give a soft answer. Encourage youth. Manifest your loyalty in word and deed. Keep a promise. Forgo a grudge. Forgive an enemy. Apologize. Try to understand. Examine your demands on others. Think first of someone else. Be kind. Be gentle. Laugh a little more. Express your gratitude. Welcome a stranger. Gladden the heart of a child. Take pleasure in the beauty and wonder of the earth. Speak your love and then speak it again.’ (Adapted from an unknown author.)” ( ed. Clyde J. Williams , 270–71).
