I often appear negative (use to be worse) and it puzzled me because I rarely feel negative. It turns out I'm not really "negative" I'm just very good at and keyed into finding what is wrong in a situation so it can be fixed! I think it's like the half empty/half full thing; if you ask my opinion on something I'll tell you what's wrong with it instead of what's right. But because I find things wrong doesn't mean I don't "like" the idea/situation, but other people can't know that since I'm only mentioning the one side. I'm actually very "balanced" and can see both sides of a situation but since one doesn't have to "fix" a good thing, I concentrate on the stuff that I can work on.
