Half-full glass for me, thanks. Someone upthread already mentioned that if they didn't focus on that, whatever blows life deals to you become incapacitating, and I've seen it proven again and again. In its way it makes sense - why bother with trying to get out of a bad situation if everything is going to the dogs anyway?
One of the great things of getting older, at least for me, is I find it increasingly easier to stop caring and shut out worry and fear, two things that have never resulted in anything other than a pointless waste of time, energy and resources. Positivity = productivity, at least for me.
