Dose success come solely from hard work？ It is commenly believed that hard work is vey important to success. In my opinion, success can not be attributed to any single factor.No people become successed by pure hard work or luck.
On the one hand, hard work plays a tremendous role in a person's success.  Albert Einstern, the famous scientist once said :"Genius is one per cent inspiration and ninety-nine per cent perspiration." That wisdom is believed by many people from different fields in different ages.  Consider scientsts. Hard work leads to great scientific success, like Marie Curie, who found the element radium after years of hard work and brought a great breakthough in her field. Consider sportsman, Hard work improves skills and win games ,such as Micheal Jordan who played a legend in the bascketball history. Consider students. Hard work helps students earn top score in tests, win scholarships and achieve academic success.I can back up with my personal experirences.When I prapared for the National College Entrance Examination, I got up at 6：00 in the morning and went bed at 10:00 in the evening everyday for a whole year. At last I got a famous score and went into my dreaming college.
On the other hand, there are many factors we can not control or work hard to make changes. These factors may lead to failure as well even though a peoplr work very hard. I believe before the final success made by famous people there are a number of failures not less or even much more than the success. And the well kown examples such as the found of penicillium genus by Alexander Fleming, which is always regarded as the case of people achieved success by pure luck, in reality is another form of success contribute to his yeas of hard work.
When hard work meet good luck, success appear. We had better waork hard to hold what we can control and not to foget there still have some unpredictable factors exist in our way to success.
