Not only does it soothe the other person, this approach is ACTUALLY helpful in improving oneself i.e. how one approaches an argument or a difference of opinion.

Not only does it soothe the other person, this approach is ACTUALLY helpful in improving oneself i.e. how one approaches an argument or a difference of opinion. Once you say this and mean it, you are no longer thinking about how wrong or stupid the other person is. You are no longer frustrated by someone else's apparent incompetence. Instead you start thinking how to share with the other person, the influential thoughts and experiences which you have already had. The sooner you are successful in letting the other person experience the same thoughts and experiences that you already have, the better the chances that the other person can now see your point of view.
