There is a famous statement that an optimist will see a glass half that is full, while a pessimist will see a glass that is half empty. The basis behind these distinctions is that people who practice optimism tend to focus on what is there.Conversely, people who possess a more pessimistic worldview tend to focus on what is missing.
To many people, the color of reality is closer to pessimism than optimism. After all, life isn’t fair. The nice guy always seems to finish last. Vast inequality exists between people and between countries that defy many people’s imagination. How can somebody possibly be an optimist? Optimism seems to be the province of a foolish Pollyanna type worldview that fails to comprehend reality.
