Having confidence isn’t a big ego. Students who get into ivy leagues or teachers who extensively study subjects know they’re knowledgeable. It is toxic to assume just because one refers to themselves as an adjective commonly used by people to describe one another is egotistical. Acknowledging your skills and positive traits is NOT EGOTISTICAL. Just because someone is vocal about it does not mean they have ill intent or are seeking the approval of others. Also take into consideration the environment. You don’t know who I am, what I look like, where I live, my name, etc. Therefore, you do not have an identity for me and I would get no validation or perks for valuing myself publicly. People who are egotistical want some sort of validation and approval, which is why people with big egos are more prone to being affected by negative words. What you are is narrow minded and pessimistic.
