This is some next level clickbait and we all fell for it. With „hard work“ he is touching on somthing we all can relate to. So we read the thing.
What he is trying to get across is: a) i know hard work, that is why i „made“ it. b) it takes hard work to make great things c) this proves i made great things.
This is not a philisophical reflection. It is marketing BS. I am not a hater. Just trying to give name to the elephant in the room.
