effort Edison one said : " genius is one percent inspiration and ninety - nine percent perspiration" . I entirely agree with this view and believe that there are many factors that make a person successful such as passion, effort and may be a little luck, but a person want to succeed must definitely work hard, while luck is just a random factor. To begin with, people are entirely responsible for their success or defeat. In fact, success in any field requires effort and enthusiasm. According to a survey , the working time of billionaires in the world is much more than the others. Fox example, Mark Zuckerberg alway come to the company very early and come his home very late, there were days when he worked from 8 am the morning before to 8 am the next morning. Or Tim Cook who alway got up at 3.45 am to work. As a result, they become successful person and famous. They are evidences that argue that by working hard , we can control our own destinies. On the other hand, there is another argument that people need luck to success. Luck factors affect to destiny of people suck as circumstance of family or country, school ... For example , if you live in the developed country , you will have more opportunities and good choices. Or , if your parent are rich and successful , you will live and study in the best place. In conclusion, in my opinion , if you do not have effort , you will not take advantage of your luck and opportunity. People can not depend on luck , by working hard , people entirely control our life.
