A quiet, peaceful home.
Growing up in a home where the rule was "if you don't have anything nice to say, don't say anything at all" resulted in peace within out family. We were also not exposed to gossip, true or false.
I later learned that this philosophy came from Psalm 34, "Who are those that desire life, and loves days, that we may see good there? Keep your tongue from evil and your lips from speaking deceitfully. Depart from evil, and do good: Seek peace, and pursue it."
Not only is this good advice to promote peace and respect, it may reward us by lifting our soul. For those hoping for eternal life, let good thoughts, spoken words, and kind deeds outweigh the less possible options.
