It can not be more truely that people usually makes the wrong decision at the end of the day when they have ran out almost all of their will，just as what I did last midnight. Instead of going to bed , I determined to accomplish my diary by staying up late, though I felt extremly sleepy at that time. A wrong decision or choice could make me in a very down mood. Now at the beganning of the "next day", a sense of frustration dominated me, because I felt so tired to get up. The frustration was accompanied by guilty. To some extent, I think that all these bad things happened for my undisciplined behavior. In other words I don't think that people failed to control their morning deserve a successful day. I know this mindset derived from a thinking style of perfectionism, and perfectionism is the source of failure. This is a pathetically vicious cycle, and it's hard to make any breakthrough with this mindset in any area.
