I have seen people in my life who work hard all their lives and achieve nothing and I have also seen people who do not work hard and achieve great success. This is a natural system but it is widely believed that you can achieve a lot with hard work but sometimes hard work does not succeed and some work is also based on luck. That is why to do it well, our previous hard work makes us better than before which protects us from mistakes. It was our own luck based on hard work and thinking due to which you will succeed and you also had to go through some problems. There are many such things that we do not know but when we think with good thinking, we get such very profitable things in which you have succeeded.
So what are you insinuating, we shouldn't work hard and depend solely on luck? I also know several people who became poor because they believed success is not a product of diligence but luck. So they depend on gambling, religious exercise and begging to acquire wealth. You don't just work hard but smart. You should always strive to improve yourself and invest wisely. You can start as a labourer in an organisation, but don't spend your entire life in that position. Seek ways to advance your knowledge and skills so that you can be promoted and earn higher.
However, I am not disputing the fact that some people might be lucky to inherit wealth or win a jackpot, while others have failed not because of laziness. But we should surrender our future to fate.
