Most of the reason that I study so hard right now is because I want a 4.0 gpa so that I can buy an island and get away from everyone.
Why do you want to get away from everyone?
People are so selfish and I hate them.
It's true that some people can be selfish, but that's not everyone and it's unfortunate that you feel such hatred. I definitely see how having such negative feelings could effect your current worldview. I would suggest trying to be more open-minded and accepting of others.
I'm not exactly antisocial, I just don't like people that much.
While you may not be antisocial, the way that you're acting is exhibiting a lot of antisocial behaviors. I think you should try to meet some new people who share the interests that you do and have other things in common. Once you connect with people who you can enjoy, I think your beliefs might change a bit.
