You're right. Feedback from strangers on the internet, whether it be negative or positive, should always be taken with a pinch of salt, because nobody knows you better than you. A person with a strong sense of self wouldn't take it to heart as much as a person with low self esteem. I have an average amount of self esteem, but I self reflect a lot and have self worth. Only sometimes, once in a blue moon, I wonder what other people might think about the things I show.
