I see myself as a "Half-Full" type of person. Some things in life can't be changed, so you have to accept them as they are and try to look at it in a positive light.
However, it this "Half-Empty" and "Half-Full" were really about drinks, I think I would be a "Half-Empty" person if it was a really good drink. (Like the green tea I had last night! It was really good, but there wasn't that much in the can. T.T)
