I remember reading about the surface area of luck sometime back and you can work hard and increase it.
What we don't realise is there is a limit to it. Once you've exhausted your allocated quota of life time of luck then the cost of hardwork to incrementally increase the surface is too high, higher then one would like to pay.
I'm not talking about being lucky to create a billion dollar company. I'm talking about having a lady at the check-in counter at the airport to allow you with 15.6Kg of baggage and not charge you for it kinda luck. I'm talking about being born in mid-tier money cushion where you at 24 and don't have all the responsibility of family kinda luck. I'm talking about freedom to pursue higher studies without having to worry about family and financials kinda luck.
No matter how hard you work this sort of things happens only when you are super lucky and cannot carve it out by hard work.
We've been brain washed into working hard.
