There are two types of criticism:
1) others judge you because they want you to improve, for example a teacher that say comments about my thesis ("I don't like this part"), and she pointed to me errors, she is doing this without hurtful reasons;
2) others criticize you but their words aren't helpful, they say things like "you are too fat, you are ugly, your hair are messy...." etc, they make comments about everything they don't like
I think the people that judge you are the 2nd type based on your post. It's funny, because since young age, people tell children "you have to be yourself, stop acting like others!" but when a person acts like yourself, in a spontaneous way, some people start to tell them "you can't be like this, you can't act different, you are different than the norm!". And this is a contradiction....society tells us to be spontaneous, at the same time tells us to conform and to act like everyone else.
If you are happy with your behaviour, with your ideas and your lifestile, and if they don't cause any problems to other, then others judgements are irrelevant. Others can jdge us, there are people who like to talk about others, or to point out irrelevant flaws...this says more about who talks than about yourself
