I think part of the optimism (in investing) is finding the opportunity in the bad. For example the best time to buy is after a crash kind of thinking. Also I would argue that most of us are more optimistic than we think, why else would we buy workout equipment or get gym memberships over and over when our past history would prove pretty solidly that what we think will happen likely won't. It's because we are secretly optimistic that it can/will happen this time. Granted this isn't true for everyone but the point that we are more optimistic than we think is in broad strokes true.
