The good thing about working in sustainability is that one can actively engage in a topic that seems meaningful and important. There is nothing more important to do on this planet. Or so I tell myself. The perpetual danger is to confine myself to the reassuring universe of concepts and discourse: how does transformation happen? Which leverage points can we address? What theory of change is the most promising? I have always made it part of my mission to go beyond discourse, engaging in the risk of radical self-transformation through practicing what I discourse about. That is one of the reasons I love to engage in experiments.
