最近总是禁不住想一个人successful不是仅仅因为how smart you are or how hard you work, but how privileged you are.  And there're always arrogance, biases and ignorance on this world, from the beginning to the end. Worse still, it's part of the truth of human society. There'll never be a day that you get up and find out everybody is treated equally by everybody else. There'll never be. It's built in our genes that we look differently and it's a fact that we come from different backgrounds. It's simply a truth that people are different on various levels. We tend to be judgemental towards others just because they are unlike ourself, either to protect ourselves or to feel superior.
