Seeing things from the other person’s point of view has a profound effect on our emotional health, since the totality of how we relate to others is dependent on this concept. When you master the ability to view others as they see themselves, you will gain the love of everyone.
Today, think of someone you find it difficult to get along with. See this person as he views himself and patiently talk to him from his perspective.
