Taking pictures of funny signs seen during travels is a time honored tradition, and I think the "Beware of Invisible Cows" one that we saw in Hawaii at the entry way to Mauna Kea is probably the best I've ever come across. Husband and I marveled at the impossibility of the request. We'd love to beware of the invisible cows, but since we can't see them, it was a slightly difficult request with which to comply. We did our best, and fortunately we had no problems.
As I was falling asleep last night, I decided that the Invisible Cows were the perfect metaphor for the things that vex me. My invisible cows are worrying about my professional life, and they take many forms. While I'm acutely aware of the invisible cows, I'm not actively trying to avoid hitting them. Instead, I wander around in the middle of the foggy cattle grounds and then wonder why the invisible cows are always tripping me up. From now on, my strategy is to let the cows wander aimlessly - after all, they are there and there is nothing I can do about that - but stay out of their pathways. Sometimes we'll run into each other, but hopefully we can more peacefully co-exist. Moo.
