In the face of helpless situations that can't be changed, if you can't change the situation, then change your attitude. You cannot rely on others for your own happiness; you can only search for it by yourself. You must learn to train yourself so that even in times of disappointment, you are still able to cherish hope and faith, and keep yourself happy. Shake off that which bothers you, and don't think about it any longer. Don't worry about future happenings, purify your soul with a fully occupied life and pursue your own happiness in the midst of living.
