"To paraphrase Jim Loehr: The power broker in your life is the voice that no one ever hears. How well you revisit the tone and content of your private voice is what determines the quality of your life. It is the master storyteller, and the stories we tell ourselves are our reality. For instance, how do you speak to yourself when you make a mistake that upsets you? Would you speak that way to a dear friend when they’ve made a mistake? If not, you have work to do. Trust me, we all have work to do."
