By Amanda

My short biography, like most quippy summaries, doesn’t hint at the most important part of my story: the bigger reason behind why I have pursued a life making change and why I wanted to write this book.

I live with bipolar. At 19 I had a psychosis and was hospitalised for several months. It was a difficult experience that taught me about the fragility of life at a time when my adult life had only just begun. I chose to make whatever life I had matter. For me that meant a life making a difference.

Over thirty years I have sought to make a difference in the world; experiencing the joy it brings – such as being part of the largest global protest in human history against the Iraq War in 2003, but also the sadness that comes when you fail to make the impact you hope for.

Through action as well as reflection, across different countries and social change strategies, I have slowly developed a way of thinking about what it means to make change by learning from its unevenness, its complexity and its paradoxes.

The power of paradox is far from abstract, it is something that I live with. My life circulates across an uneven temperament that has taught me to be observant of change and to be respectful of what I cannot control. I have learnt to recognise that public life has contradictory dynamics too, and through traditions like philosophy, theology, community organising and democratic theory I can see how paradoxes can help us make sense of our agency and clarify the kinds of choices we might have to make a difference.

The book puts flesh on the bones of this story, including some of my more difficult and painful experiences. But at its core, what I found and what I want to share, is a story that celebrates our agency. Even in the face of obstacles and challenges, we all have the power to write a new story about the difference we can make in our own lives and in the wider public world in which we live.
