You cannot avoid making judgements but you can become more conscious of the way in which you make them. This is critically important because once we judge someone or something we tend to stop thinking about them or it. Which means, among other things, that we behave in response to our judgements rather than to that to which is being judged. People and things are processes. Judgements convert them into fixed states. This is one reason that judgements are often self-fulfilling.
