The purpose of this book is to inspire you with many examples of applying ‘Less is Beautiful’ within your own professional life. As a consequence, I have visited an enormous amount of websites and blogs; watched dozens of youtube movies; been in touch with many people; read many articles, discovered several great slideshares and buried myself in a few books to create this book. To honor the authors and sources of all this inspiration, I’ve made a list of the most important sources - in random order.
