To experience the strength and delight of taking action whether faced with a challenge or an opportunity, we all need agency. But in order to avoid arrogance and injury, we also need humility and self-control. In order to have faith in our creative ability and exercise caution in our work, we need reliable and testable navigation tools. We're all looking for tools to help us navigate the complicated, noisy, and contradictory culture we live in, not solutions. One of those instruments is a manifesto for one's own life. You Need a Manifesto describes The issues of the information overload we all experience today are first defined by Charlotte Burgess-Auburn, director of community at the d.school. She then discusses the significance of developing a personal slogan or motto. Animated quotes and excerpts from a carefully curated collection of designers, artists, writers, scientists, and social activists are intertwined into explanations and practical design-based exercises. These sayings provide the activities with both motivation and material. In order to help and inspire you to see what you can generate for yourself, each chapter of the book is also accompanied by a graphic by artist and letterpress printer Rick Griffith. Griffith's designs were inspired by the content of each chapter.
