I heard a story not long ago about a man who was always thankful and didn't complain. I don't remember the whole story, but one day the weather was awful and there were a series of other unfortunate events for this man. His friends thought surely he would complain, and when they went to him they said, "you can't possibly find anything to be thankful for today." He said, "Oh, yes. I am thankful that every day is not like today."
So, that being said, I'm not going to complain about yesterday. I'm just going to say, "Lord, thank you that every day is not like yesterday, and please give me wisdom and strength for today. AMEN"
