For a single person,aims are the major source of motivition.Like a compass hold by a brave explorer guiding his owner safely arcoss the mysterious ocean,aims do the same affairs that compasses do.Without a aim,one may get lost in the very hectic daily life,and may thoroughly lose faith,not knowing what to do.Thus,he can never succeed.
All in all,we should have a aim---no matter what it is,we should have a faith to hold,to believe.That will do a lot in our choosing a major direction to head for.And after a long fighting process,we will do achieve our ambition and get what we want at last!
