Not so sure. I've met enough people whose only wish was to make a lot of money, yet who failed to achieve it. In a competitive environment, you almost certainly have to be ridiculously good at something else (anything from programming, I suppose, to brain surgery to dealmaking to leadership) to make a lot of money.

Also, Rockefeller's quote applies in the sense that, once you make a lot of money, your definition of what "a lot of money" is changes.
