Sucess is always considered as the combination of both hard work and luck .People donot tend to appreciate the role of luck.However,in my opinion, luck is possibly the most important factor deciding whether people are success or not. Firstly, luck often leads to significant changes in various circumstances.It might have positive influence in the result of people’s goals.That is because of many factors that control human’s life, such as nature matters. For example, in the countries that have agricultural policy, farmers have to work hard to take care of their fields for a long period. In the theory,they must have achieved favourable outcomes.However,if a disease occurs,no matter how hard they have worked, their havest will be ruined. In this case, it cannot be denied that luck has an unreplaceable role in daily life Secondly,there is no doubt that success can only happened when a person have chance to show his or her hard-work result.Reality proves that never mind how untiringly one has been working, it will become nothing without opportunites. An illustration of this is Celine Dion, who has a beautiful voice since she was a child.Nevertheless, she was unknown until a manager recognized her talent and signed a contrast with her. She then became one of the most famous singer in the world.There are many singer who has been trained, but she is the chosen one, that is why she is fortunate. Obviously, it can be refered that the pure reason for success is luck. In conclusion, luck is one of the most concern issues that has a great impact on human’s success.People may work hard, but in order to be triumphant, they have to have luck.It happenes not only in a few areas but every aspects in the society.
