终于把HDU的第一页做完了

Today is worth to be commemorate for that I have eventually worked out all the questions in the first volume.Em,I registered my account in maybe April,and it has been three months so far.
In fact,I am kind of surprise when realized this.In my impression ,I think I nearly finish nothing in the last term,even last year.To be frank ,there were just a few subjects for me to learn last year.There are almost ten or more hours for me to do what I want.In the former term ,sometimes I have to do my assignments.But in the latter term ,the truth is thar I learn totally nothing from my teacher,neither homework.Moreover ,I was absent from most of the classes.So you can see I owned nothing except spare time.But what did I accomplished in the end? Nothing!You may have noticed that the word "nothing" has the maximum frequency of appearing.That is what trouble me most.I can ignore my low score in the exam,and the absence from class ,but I can't excuse myself of wasting time.
Let me recollect what I did and how long did it took.
Play mobile phone games.This often happen when I was attending classes or when I was lying on bed before sleeping,or sometimes I felt bored.
Play computer games.From last term ,I began palying computer games.PAL3 took me nearly a week,and battlefield2 took me dozens of hours,while Call of Duty 46789 took me at least hundreds of hours.
Watching TV.Last term I download 15 TV drama programs,and went through all of them.This occupy at least twenty complete days.
The three points above is where most of my times went.In the remain days in summer hoilday,and further more in the next year ,I hope this would not become my essential problem.And at least ,do not waste time anymore.
