Well I don’t agree with what teachers tell us. Hard work can get you somewhere yes but it wouldn’t be the only thing you should do in order to succeed. In my opinion you need a little bit of luck still. Hard work plus luck is the deadly combo. That would get you anywhere you want in life and further. Though not all of us gets that lucky.
I agree with you, not all things that our teachers taught us is true, some of them is kinda biased because there are people who are born rich and that is because of their parents' hardships or they actually came from the family of the rich. some people is working and striving hard to become successful because that's what imprinted in our mind but if you see some people still not successful and can't see that they are rich, some of them still earning enough for their day to day needs. Sometimes, it's not all about working hard, we should accompany it with practicality, determination and being strategic, we need to atleast learn how to manage our financials, so on and so fort.
