Is Your Glass Half Full or Half Empty？ Please help me correct it. Thank you! === This is a well-known psychological hypothesis: When you see a glass filled halfway with water, do you see it half-empty or half-full? At some level, the answer reflects if you are an optimist or a pessimist – things are how you see they are. Most of unhappy people tend to say the glass is half-empty. When people in depressive mood observe a situation, an activity or interaction, they often make negative hypothesis and expectation. Unhappy people unconsciously consider bad traffic, raining, and paying bills as passive experience. However, the nature of traffic, weather and bills themselves are neither positive nor negative. It is your choice to give them a positive or negative purpose based on certain circumstances.
