As a child, textbooks and teachers have taught us that hard work begets good luck. That is, no one comes into the world with luck, everyone has to make their own luck. The more hardworking and the more serious he is towards his work, the more likely he is to succeed. But there are some people around who look at them and think this saying is not true. Around me, I see many such daily wage laborers, rickshaw pullers or agricultural laborers, who remain at the same position from which they started their life even at the end of their age. It's not like they don't work hard. 

A day laborer works for around 12 hours non-stop and in return they get a small amount of money which they spend in various ways. Here my question is why they are not able to change their fate after working so hard.  In this case you may tell me that he is a daily wage laborer or he is a rickshaw driver that is why he is not progressing but he is focused on his workplace and he is working there with full focus so why is he not changing his fate. If a rickshaw driver or a day laborer wants to but cannot become a doctor or an engineer, he has to focus on his profession. What do you say about his change of fate?
