I was once doing a radio show about our (my and my father Dr. Robert Firestone’s) work on the “critical inner voice.” The host started the show by talking about all the media attention on terrorism and the fear we, as a nation, were feeling following the attacks of 9/11. She ended her introduction by saying, “But what if the worst enemy we face is the one residing inside ourselves, the critical inner voice?” I found her statements compelling. Throughout our lives, we often act as our own worst enemy, sabotaging our success, undoing our relationships, hurting the people closest to us, and not really living our lives based on the things that really matter to us and that would give our lives meaning.
