How do you know what problems do you have with the surrounding world? It is necessary to perform an exercise. It is necessary to sit down, take a sheet of paper, a pen, and answer a question "What annoys you in other people, in other men, in other women? Which qualities of character do you consider as unacceptable?" All that you write is your PERSONAL problems, that you feel with the surronding world and that prevent you to live more happily.
