“Is the glass half empty or half full?” is the proverbial phrase to indicate that a particular situation could be a cause for optimism (half full) or pessimism (half empty).
There’s a THIRD WAY you could look at it. You could look at the glass as “half empty AS AN OPPORTUNITY” as opposed to the old way of “half empty AS A PROBLEM”.
So suppose you say, “I don’t like my job and I’m not getting another one.”
.. the pessimist in you will say “You’re in a soup!”
.. the optimist in you will say “Count your blessings.. at least you have a job! There are millions who don’t.”
YOU could look at the same situation and say, “What opportunity does this present to me? What is MISSING here that I can address?” (which puts you in the driver’s seat and propels you into action).
MORAL OF THE STORY: Stop wondering whether the glass is half-empty or half-full and START FILLING IT!
