All of us want to do our preferable things and tend to avoid troublesome or difficult task as much as possible.  However, I think that we sometimes have to do what we do not enjoy.  There are two reasons we have to do the job against our will.

 

  First reason is because our doing the troublesome job is necessary for others.  For instance, we sometimes hear the news that criminals go to police for themselves thanks to the persuasion of their intimate people such as their friends or parents.  In these cases, for the criminals' parents and friends, persuading the criminal is reluctant job since they do not want to relate these things and might even want to deny the astonishing fact that their loved person committed a crime.  However, they dare to do the important job.  It is because, I guess, they realize that they are the only people who can persuade the criminal and prevent him/her from committing crime again.  In short, they do the touchy task not for their own benefit but for their loved person and common good.   As this example shows, if possible, we sometimes have to do troublesome things for others.

 

  Second reason is that doing the task is necessary for us. If we have diabetes, we have to limit calories of meals and cannot enjoy dining so much.  However, if the patients stop diet, diabetes will develop.  Therefore, such people reluctantly cut down the amount of sugar, fat, and grain for their own health.   We also study hard before taking examination, even of we do not like studying very much.  But taking bad score or escaping from the hateful exam itself must lead much  more disadvantageous situation in our career and future.  Without graduation from certain school, in my country, Japan, we hardly get our favorite or ideal job.  Therefore we reluctantly study hard to take satisfactory grade at school, even if we dislike the subject. 
 
  In this way, some jobs that we have to do by force are necessary either for others or for us.  Therefore, we sometimes should do what we do not enjoy doing.
