Is the glass half-full or half-empty? How you see the glass all depends on your perspective. Maybe you have heard that some people are glass-half-full kind of people and others are glass-half-empty people. The idea is that people are either optimistic or they are pessimistic. I don't think how you view this glass of water determines what kind of person you are - humans are more complicated than that. However, if you choose to be more optimistic about things, you choose to look at the brighter side of life. Or what I like to say, "Look for the good." Check out this video and let me know if you agree with what I'm saying about optimism.

Optimism is hopefulness and confidence about the future or the successful outcome of something.
