One piece is communication. We need to listen to each other, and to speak from our softened hearts. Judaism takes the power of speech very seriously. God created the entire universe with a word. In Hebrew, the ten commandments are not known as the 10 mitzvot, rather, they are called the aseret dibrot - the ten words.
Authentic speech is considered the beginning of the path to true tshuva , repentance.
The story is told of a woman named Sarah who had fallen into bad ways - she was a thief and also an informer to the authorities. She asked how she might repent, but she wanted to do it in a fairly easy way. Just decide to give up one single misdeed, the act of lying. That doesn't sound so bad, she thought. So she made an agreement with the Hacham that she would never again tell an untruth.
