I'm sure many of you are familiar with that adage. Some of us see the glass as half empty, others as half full. If you're a half full type, you are supposed to be the more positive of the two thinkers, right? I see it a bit differently these days. Here's why...
Now this "glass" is a metaphor for many things. It can be our life's work; it can be our material possessions; it can be our overall happiness with life. Whatever you think the "glass" is doesn't really matter. It's the attitude about the "glass" that matters.
If my glass is half anything, then I can assume that I don't have the other half, right? It's missing. Or maybe I never had it. How do I get the other half? If my glass is half full, it seems as though someone else has been doing the filling, and in turn, it is up to them to finish the job. If my glass is half empty, it seems more likely that it is up to me to fill the rest. (A purely pedantic exercise, I know, but hang with me.)
If this is the case, I prefer seeing the glass as half empty. It gives me the responsibility of filling up the rest. Furthermore, if I don't like what is in my cup already, I can change up the mixture. 50% of my glass may be rancid sewer water, but I can fill the rest with clear spring water.
For now, I'll stop looking for the waiter, and I'll fill my half-empty cup from the tap in my kitchen instead. It's not a mountain spring, but sometimes the best "water" is right under your nose.
