Already talked about Warren to the other comment, but let me give a different angle. In Warren's early days he had insane business ideas and some worked, like selling used golf balls by swimming in ponds at courses. He learned a lot from action too, when he got to college he had 100k savings so he could then afford the theory. I think he proves most that doing both is best.
