If you need a definition of hard work I'm sure you have no success in your life unless your dad gave it to you on a silver platter.
If you can't define HARD WORK, you obviously have no idea what it is. If someone finds mathematics easy and natural and easily obtains high qualifications without much difficulty and effort, is his success not as deserving as someone who always struggled with math, needed extra tuition, failed many times along the way, but stuck to it and finally accomplished the same as the person for whom it came naturally. They are both successful, but one struggled and suffered a lot more than the other. Does your definition of HARD WORD mean consistent suffering in the pursuit of a goal?
And in my life, I have had varying degrees of success, but I can tell you the time I made the most money and others said I was most successful was far from the hardest I had worked. I worked hard in my teenage years and early twenties with very little success or money. hard work being equated with success is a myth, and if that was the case, SLAVES are the most successful people.
