This essay is dedicated "to you, in particular, if you have failed recently or spectacularly." With vivid examples, the essay challenges our assumptions about the nature of failure and suggests five tips for successful failing. "Think of failure like a scientific experiment. This little booklet will help you understand what variables matter, recognize how they work, and make meaning of the results. You will discover that a failure provides you with a window of clarity, a gift of wisdom." — Robin Mount, Director, Office of Career, Research, and International Opportunities, Harvard University.
