There are builders and market players.

They are not to be confused. Very few market players do anything great. After a while, it is only money.

What makes names like Bezos, Musk, Jobs, and Ellison so well known? Sure they were extremely wealthy. But they built and continued to do so even after they were rich.

Does Elon still need to put in 100 hours per week? No. He could buy and island and live on it. Yet he still pursues massive projects to alter the path of humanity.
