Work, on one small doable rather than many large undoables. Almost always, it is a laughably small wound that causes the first hurt in relationship. But then, ignoring the smallness lakes on a size of its own. Ignoring the problem becomes larger than the original problem. Develop forgiveness skills.
Forgiveness looks forward, vengeance looks backward.
Purify our hearts. Sometimes the conflict partners are so emotionally wounded or ideologically hidebound, that nothing con stop the violence. But large numbers of conflicts can be resolved without killing or wounding the other side, provided the strategies for peacemaking are known.
