Maybe this is blase, but I find this sort of grindset thing weird because Jay Z would surely have helpful things to say, but in addition to getting lucky, his expertise for how to go from pleb to rich would be based on his own experience of exploiting a system that has changed a great deal since the time that he got which and has hardly needed to even consider what it’s like for the little people. You’d be way better off asking a soundcloud rapper who recently became a millionaire rather than an older rapper who became a millionaire in the previous century, because all of his more recent information about parlaying massive wealth and fame into even more wealth aren’t that useful to someone who isn’t already rich and famous.
