As we develop new beliefs about who we are, our behavior will change to support the new identity. The same thing happens with a person who has excess weight whose identity is, “I’m a fat person.” This individual may diet and lose weight in the short term, but he will always gain it back because his sense of certainty about who he is will guide all his behaviors until they are once again consistent with his identity. We all must maintain the integrity of our convictions of who we are, even when they are destructive and disempowering.
