Everyone wants to be happy; happiness is a right. And while on a secondary level differences exist of nationality, faith, family background, social status and so on, more important is that on a human level we are the same. None of us wants to face problems, and yet we create them by stressing our differences. If we see each other just as fellow human beings, there'll be no basis for fighting or conflict between us.
I can only think seriously of trying to live up to an ideal, to improve myself, if I am split in two pieces. There must be a good “I” who is going to improve the bad “me.” “I,” who has the best intentions, will go to work on wayward “me,” and the tussle between the two will very much stress the difference between them. Consequently “I” will feel more separate than ever, and so merely increase the lonely and cut-off feelings which make “me” behave so badly.
