" That’s the thing about mindset interventions: They seem too good to be true. They contradict a deeply held cultural belief about the process of change itself. We believe that all meaningful problems are deeply rooted and difficult to change. Many problems are deeply rooted, and yet one of the themes you’ll see again and again in this book is that small shifts in mindset can trigger a cascade of changes so profound that they test the limits of what seems possible. We are used to believing that we need to change everything about our lives first, and then we will be happy, or healthy, or whatever it is we think we want to experience. The science of mindsets says we have it backward. Changing our minds can be a catalyst for all the other changes we want to make in our lives. But first, we may need to convince ourselves that such change is possible. "
