Also, do not try being friends with people because of what you stand to gain

This is one of the mistakes some people do, they only want to associate with people bigger than them forgetting that those people won't easily accept them because they know their intention, discrimination is a bad thing to a certain level, oh this person is not as rich or great as me, i wont interact with him or this person is just a newbie as i am, i don't want to interact with his acc forgetting people below them can know someone above them and even refer them if they possess the skills those people want which they lack.
