the different between "使命" and " 任務"


the different between "使命" and " 任務" .i looked up dictionary and they are the
same meaning "mission"




Both "使命 and "任務" mean an mission. The difference between them is the degree
of difference.  
  
"使命" is the mission nobody else but one can do, and one should become aware of
its importance. On the other hand, "任務" is indeed not "task" but "mission".
However, the importance of "任務" is less than that of "使命". Here are example
sentences:  
  
私の使命はこのチームを優勝に導くことだ。/ My mission is leading this team to victory.  
私は上司が出した任務を終えた。/ I have accomplished the mission my boss ordered.
