Impact is widely touted as the key driver to implement the 17 UN SGDs. But much work needs to be done. For starters we need to dynamically co-create and develop our own capacities and our organisations so that we can build a sustainable, effective architecture. This book is about redesigning our self, our institutions, our economy, our system of finance, and what we mean by investment so that we can build that architecture. It is a book that I spent a lifetime writing, a book that took me on a fascinating journey-a journey that I'm happy to share with you.
