Worry is today's mice nibbling on tomorrow's cheese.
(Matthew 6:34 So don’t worry about tomorrow, for tomorrow will bring its own worries. Today’s trouble is enough for today. (NLT))
I have been going through a computer conversion at work, have spent many extra hours preparing, and was uneasy as to how things would go when we went "live". Well, Thursday was the day, and although a little slow, it was a smooth transition.
I spent energy worrying about a problem that didn't happen. Hmm, lesson learned, I hope!
