Are you someone who sees the glass as half-full, or half-empty?
I’ve always thought that was an odd way to determine optimism or pessimism.
To me, it’s irrelevant. The only thing that matters is, how much liquid is in the glass? If it’s an 8-oz. glass, just tell me that it has 4 oz. in it.
Anything else is pure conjecture.
I guess that’s what comes from being a science geek.
