Are you as sick of that whole glass-half-empty/half-full saying as I am? Not only is it clichéd, it’s a ridiculous analogy. How you see a glass has nothing to do with your optimism or lack thereof.
When you are filling a glass (or any container) and you get to the halfway mark, the glass is half-full.
When you are emptying a glass, either by pouring out the liquid or imbibing it, and you reach the halfway mark, the glass is half-empty.
It isn’t how you see the glass; it’s what you are doing with it that matters.
So, now that this particular cliché has been declared deader than a doornail, (another ridiculous cliché that is so dead it stinks) can we bury it and get on with life?
