Why I'm an Optimist

Is the glass half-full or half-empty? We’ve all heard that it depends on whether you are an optimist or a pessimist.

But what if the glass is filled just short or just above the half-way mark?

Published research shows that pessimists are more frequently right; they are in better contact with reality.
