缃盈居

  昏天黑地的在宿舍里忙了一天，心情反而越来越好

  The more one has to do or one is into,the greater the involvement is in a mental,physical or social way in these things.Due to this,one's own personal problems  are out of sight,because at this time one's mind is full of compeleting the undertaken tasks.

  Problems,one's they are out of sight,out of mind.

  尽管凑出来的论文没有多大价值，但起码占去了用来想起不愉快的时间

  pain past is pleasure.
