Today's world seems like it's just one conflict after another in all walks of life. We have conflict between countries over their borders, conflict in our schools, conflict in our work environment, and last but not least, conflict among our children.

I definitely think that conflict resolution is a valuable skill for people to learn. There are a lot of instances in people's lives that they will face a situation where they might need to settle an issue or problem between people. I think if somebody is good at resolving conflicts, it is valuable.
Yes, conflict resolution is a valuable skill, because it is something that will help no what a person wants to do. If a person is a bartender, conflict resolution is a good thing to know. Likewise, if a person is a lawyer, it will be helpful if they know how to resolve conflicts.
