Optimism is hard for a reason – it’s unnatural. For our ancestors, being optimistic and “wrong” perhaps meant you missed out on an opportunity, whereas being pessimistic and wrong meant you became tiger food.
We should train ourselves to overcome this programming for a few reasons: First, many of us are lucky to live in a world where we can test theories, and create things that might be valuable. We can be wrong and “fail” many times, often with little to no personal or reputational damage, unlike our ancestors.
Second, being optimistic is a healthier mindset regardless of outcomes. And lastly, you’re more likely to improve the world (and yourself) by thinking “this might work” versus, “here are all the reasons this won’t work.”
