While I was wondering whether what it takes to achieve that ultimate success in anything I am engaged in, it is the minimum hardwork it takes to complete it. That hardwork requires a complete soulful interest that can make you do it for longer hours consistently without getting tired. This much interest is very impossible looking task, that does not happen so easily to everyone else unless some other greater power is not there to make you continuously work for it. For example if a kid likes playing video games and he has a very strong interest in playing such games. Even if you leave him/her for as many hours or days or weeks or months, there will come a moment when that kid will stop feeling much interest in playing the game. So if he could not stay interested in doing something that pleased him so much then how can we expect that kid to open his books and study for longer hours daily and continuously till he gets his graduation and then job. And even after that work for the job continuously everyday till the day he/she retires. This is a very difficult question to answer that changes all our lives completely different from each other. For those who are able to maintain that interest for longer periods are able to do bigger tasks for longer durations and thus are able to hold much longer than others and achieve much more than others. So the problem that we here is that "how to maintain keen interest for hard work continuously for infinite period of time ?" There has to be a stimulus that keeps probing you to have enough interest in working hard to achieve your goals. Usually people have relationships which make them work for longer hours. Almost everyone has someone for whom they work to fulfill their dreams. Very rarely, a person is able to work so hard for themselves. Parents work for their kids, Kids work because of their parents, some people work for their spouse, some also work for their country. Whatever the reason maybe, we all are working for someone else or should I say using them as a stimulus to work hard. But not everyone is able to harness that energy. They are not supposed to maintain the flow continuously. It is easy to start but not easy to maintain it. So how to maintain this flow of interest to work hard continuously forever ?
