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?
Hard work is indeed the key to all success, but better than that success is education that supports the job/profession they hold/do,
If you say that a pedicab driver turns into an engineer/doctor, that is impossible because if they have an educational background, they can change their destiny, but on the other hand, if they don't have an appropriate educational background, they can't do that job.
