The document discusses the concepts of certainty and uncertainty. It notes that on earth, three things are certain: change, the end of life cycles, and that time cannot be stopped. However, it also discusses how life, desires, behaviors, risks, and forecasts are uncertain. It argues that while uncertainty is a driver of change that leads to new certainties, one can negotiate and hedge against uncertainty through innovation, exploration, and adapting to change. The only true certainty is that change is constant and one must accept uncertainty to aim for innovative and sustainable futures.
