Be extremely honest with yourself,it is a good exercise.（对自己极端诚实，是一种很好的练习。）
We are never so defenseless against suffering as when we love.（我们爱的时候对痛苦最不设防。）
Conscience is an inner feeling,it is an rejection of some kind of abnormal desire that moves within us.（良心是一种内心的感觉，是对于躁动于我们体内的某种异常愿望的抵制。）
——西格蒙德·弗洛伊德
