If optimism is important, it's because many outcomes are determined by how much of it we bring to the task. It is an important ingredient of success. This flies in the face of the elite view that talent is the primary requirement of a good life, but in many cases the difference between success and failure is determined by nothing more than our sense of what is possible and the energy we can muster to convince others of our due. We might be doomed not by a lack of skill, but by an absence of hope!
