As far as I'm concerned, hard work is much important than intelligence. Firstly, as known to all, a knife will not be sharp if not sharpen regularly. The same is true of studying. In other words, unless you don't study hard and only depend on your intelligence, perhaps you can get some achievements and stand out in the beginning. But it is no doubt that you will fall behind those whom work hard in the end. Secondly, most great people, like Edison, were not smart at the school, but they get lots of achievements through hard work. However, it proves that hard work can help you to make progresses in study and become a great person.
