When you feel disappointed, you are feeling deprived of something you thought was already in motion. If you're feeling like you have an "appointment" with a promotion or a successful presentation or a new love, having that thing not work out is especially crushing because it was kind of a done deal inside your mind.
I escaped the cage and found freedom from the wood pellets and stale feeder food. Maybe certain people tried to look for me; maybe they didn't. I didn't care. I was a hamster with a plan. I came to a fork, took the road less traveled and began running like my life depended on it (and hey, maybe it did).
