Is the cup half-full or half-empty? The optimist sees the cup as half-full, the pessimist sees it as half-empty. It’s a question of attitudes – do you see the good or the bad in situations? Though this might be a long-lived debate, when looking at the glass, I don’t see it as a question. I see it only as reality. What are we actually seeing? What is there, and what isn’t? What is inside my control and what is outside of it?
