I've written about judging others before, but I recently read something about it that made me think a little and realize that it was completely true.  Several religions teach us that it is wrong to judge others, yet we do it all the time.  The reason is simply egotism.      We believe that our opinion of something is important.  Further, we believe that others want to know our opinion, our judgements so they can either share them, or make corrections if they are the ones we are judging.  And it isn't just people.  We judge everything.  We don't care that someone spent months composing a song and working on the recording.  All that matters is do we like it.  We don't care that a cook spent hours preparing a meal for us.  We still have to mention that, in our very important opinion, it needs a little more salt (someone once told me the reason you usually don't see salt and pepper shakers on the table in Chinese restaurants is because adding things to the food that was prepared is considered an insult to the cook).  
    We also tend to think that our opinion is shared by everyone, or at least everyone of any significance.  I remember once, quite a few years ago, when I was at a movie theater with friends, we heard a group of girls, probably ten or eleven years old, discussing movies in the lobby.  One of the girls told her friends, "I don't know why they made a second Star Trek movie, nobody went to the first one."  Of course, what she meant was her and her little friends didn't go to it, so that meant nobody did (actually it was a very successful movie).   That sort of thinking is laughable in a child, but not in adults.  
    We need to get away from the idea that we are supposed to judge everyone and everything around us because our opinion is important (at least we think it is).  A simple way to start toward that goal is to stop stating our opinions and judgements in absolute terms.  Instead of, "That movie was awful!", say, "I didn't like that movie."  Instead of, "that painting is ugly", say, "I don't understand that painting.  It doesn't make sense to me."  That may not seem like much of a difference, but at least then you are stating your opinion as yours and nobody else's.  Then you can move on to the next step of listening to others who have different opinions.
