It is okay to be wrong.

We sure like to play the blame game. It's not our fault, it is that other person, that other group. The reality is usually more of a two way street. Often mistakes have been made on both sides. 

It is okay to be wrong. We all make mistakes. I make a lot of mistakes. And I feel owning up to my own mistakes is the right thing to do. How can I blame someone for something if I had the ability to avoid to problem in the first place and I didn't? It's okay to screw up and waste time, everyone does. If you were perfect, you wouldn't be where you are. We have forgiveness and we often can right the wrongs with a little more time and effort.
