A deeply thought provoking question. I did go through other’s responses and saw that most of them did not want to be anyone else. Well, I have a weird response to this.
I want to be the person that I dislike. I try most of the time to empathize with the person I interact with. But, I am no sort of saint. I do have people that I strongly dislike and no matter how hard I try I just cannot understand why are they being mean to me.

I know that there are people who are “pure evil” and I certainly would not be able to handle being them. But I want to know why the people I dislike have developed that certain trait which irks me. Maybe if I understand them better I can learn to be less effected by them. By doing so, I feel I can finally let go of the all the hurt and pain and then start to heal.
So, as you can see a purely selfish motive. But what are your thoughts? Am I being naive?
