Communication is a powerful tool. Words have the power to hurt, heal, inspire, motivate, or isolate another person. Most people, particularly those that are judged on their words, like politicians, leaders, and those in the media, are careful about what they say. Imagine how powerful it would be to choose what you say to yourself as carefully as you choose what to say to others.
When I started to pay attention to my internal dialogue I realized that I said things to and about myself that I would never say to or about another person. When I started to be more discerning about my internal dialogue I noticed how much better I felt about myself and what was going on around me.
