"Judging someone does not define who they are it defines who you are."
Everyone judges. We judge others because it makes us feel better about ourselves. Unconscious self-gratification. We judge people because they either have something that we don't have or they possess a trait that we don't like in ourselves. We have insecurities about ourselves so we project our judgement of ourselves onto other people. Our judgement on others is an extension of our own self judgement; and self-judgement is so ingrained that we now don't think anything of it. Our internal monologue to ourselves can be very harsh; if you can't be nice to yourself how do you think you are going to be nice to other people?
When we are seeking change in ourselves we usually seek change in our surroundings also. The outer world is a reflection of our inner world; if we are happy and content with ourselves we will start to be happy and content with our situation. You could be in a really horrible situation, but looking at it optimistically and keeping your mind open will make it so much more bearable to live through. We also judge people because of what they have that we don't. We are envious of them. It's the human condition: we constantly want things that we don't have, so we judge others for having the things we want but can't obtain. Sometimes judging can be a good thing. Judging situations or judging people's actions to create a baseline on how to interact with other people. Assessing situations and people.
I feel like social media is a great medium for the growth of judgement.
We judge other people's lives through the screen. We are constantly bombarded by people who have "better" lives than us. Richer, stronger, prettier people who we can compare our own lives to constantly. But people only put the good parts of their lives on social media, making social media a horrible thing to compare anything to. Social media isn't the real world; what people post isn't always the truth on their own situation. There could be so many things you don't know just by looking at a picture. Everyone has their own problems and social media just sugar coats it. Social media makes you judge yourself more because you don't have what all these other people have and that makes you feel bad about yourself. Therefore projecting your insecurities onto other people.
We all make snap judgments of everyone we meet, but we don't really know all the people we judge. We judge on the smallest things to the biggest things. If you're not 100% okay with who you are, you are going to judge other people. That's okay, but always making a conscious effort to stop assuming you know is a good place to start not judging. We don't know what other people have gone through to get where they are today.
