It isn't difficult to be non-judgemental. Just be. But sometimes we do fall into the evil and we decide a person before we really get to know him/her. But the difference between us and them is that we are AWARE that we are judging when we judge. And we are ready to let go of the judgements once we have the opportunity to get to know that person better.

I won't give a shit if I was judged. It would only make me pity you because you are the one with the closed mind. No, I won't "judge you back" and conclude anything about you. But knowing that I was judge by you only makes me see you better. And there is no need for me to try to change your idea of me, to try to prove myself to you. In the first place, I am tired of people trying to show each other who they think they are, not who they really are. Be truthful to yourself. How can one be sincere to another without being sincere to oneself?
