Your lights on it? Where the real (a) problems found

    First, the first chapter - Chapter III
     understand the problem
        (1) who encountered problems
        (2) What is the nature of the problem
     to solve the problem
         (1) the difference between the ideal and the reality of state
         (2) Fantasy problems are real problems
         (3) by having "something worse" to solve the problem
    first and second chapters explain the cause through a background story and story development, and leads to how to think correctly (who met the problem, the nature of the problem )
fundamental contradiction deal with the problem is for both sides to reach a consensus.
     The third chapter is mainly about how to solve the problem of Peter.
 Workers imagined elevator only take a short time it can take, and the reality of the elevator is to wait a long time to ride. As long as we let the workers feel
      that they wait a short time can solve this problem. At this time Peter thought through fitted mirror (due to the vanity, there are people in the elevator on each floor next to
      their dress will check the place of the mirror, do some fine-tuning), so that staff was waiting will not feel waiting too long.
 Solve the problem of graffiti on the mirror, in essence, is to solve the waiting time workers fantasy, look in the mirror and graffiti can also pass the waiting time workers.
      All there is no need to spend a lot of manpower and resources to clean up the graffiti, but also as a palliative approach.
 When it comes to the postscript "Do not take the pains to help people solve the problem of a lack of sense of humor," as I understand it is this: we can do some daydreaming, the brain can open a number of large holes
      if the case really work it! For example, if the story really extend Mr. Diplodocus take jokes and try to think Peter will have to try a different outcome.
