One of the mottoes that Diego Rodriguez and I use at the Stanford d.school is “failure sucks, but instructs.” We encourage students to learn from the constant stream of small setbacks and successes that are produced by doing things (rather than just talking about what to do). To paraphrase our d.school founder and inspiration David Kelley: “If you keep making the same mistakes again and again, you aren’t learning anything. If you keep making new and different mistakes, that means you are doing new things and learning new things.”
