Do you believe in lucks

There is no doubt that many a person strongly has confidence in luck when performing personal activities nowadays. However, from my point of view, I significantly agree that luck may not decide all of the results of our actual actions. For instance, being a suitable working attitude can bring the employee to a higher position and get more bonus payment; which will not occur unless only trusting in the lucks. Moreover, from the perspective of students, they should carefully prepare for the high-school final exams in order to achieve the high scores leading to enter their expected university; that cannot come true if they are completely based on a lucky miracle. Overall, an almost outstanding achievement may result from human patience, a high level of effort, and knowledge; excepting a little bit of luck.
