Bartlett draws on psychology and neuroscience to make an uncomfortable argument: most of what limits people is not external. It is the story they tell themselves about who they are. The self-story is the narrative you hold about your own identity, capabilities, and place in the world. It is built gradually from experience, from what people told you growing up, from the things you tried and succeeded or failed at, from the comparisons you made with others. Most people are barely aware of their self-story because it is so deeply embedded it feels like fact rather than narrative. But it is a story, and stories can be rewritten. Bartlett argues that the most important inner work anyone can do is to examine their self-story with the same critical eye they would apply to a business pitch: Is this actually true? What is the evidence? What story would serve me better? He is clear that this is not about delusional positive thinking. It is about identifying where your self-story is holding you to a smaller version of what is actually possible. The person who believes they are not creative will stop noticing creative ideas. The person who believes they are bad with money will stop trying to understand it. The belief shapes the behaviour, which reinforces the belief.
