I have a huge superiority complex.
Really? Why do you feel you have a superiority complex?
I just think that I'm better than everyone else.
Having high self-esteem is great but you shouldn't arbitrarily feel you are better than everyone else. People will likely think you're rude and arrogant and just want to avoid interacting with you.
I don't have to because I am better than everyone else.
Again, it's good to have high self-esteem but as a person you are inherently no better or worse than anyone else. Everyone has things they excel at and things they don't and that's part of what makes us human. Try to understand that and you'll have much better interactions with people in the future.
