We cannot be perfect in whatever we have chosen to do. But we can work hard at it and perform the best we can be. So why worry over what you are not doing right. Instead, worry how you could do better.
In reading C S Lewis' Screwtape letters, I come to understand a little more about the purpose of our creator.
