We all know that lots of things can go wrong with our faces! And we depend on mirrors to tell us what is wrong. A man does not want to go out in public with blood on his collar from shaving. And a woman doesn't want to be seen with lipstick on the end of her nose. So, we look in the mirror. But what would you think about a person who looks, sees a problem and then fails to correct it? You would say that there was absolutely no point in that person looking in the mirror. Looking in the mirror only works if it leads to action. Otherwise, it is useless.
