"Fail fast, learn faster." "Celebrate failure." "If you're not failing, you're not innovating." The entrepreneurial world is full of calls to embrace failure as a learning tool. This idea is well-meaning and, in theory, correct. Real innovation carries uncertainty, meaning many attempts won’t succeed. Learning from these failures drives progress. In my post on Pixar Animations, I noted that embracing failure is an important element of its entrepreneurial culture.
