Or about anything at all really. I find his blog posts and talks banal and boring, or self-aggrandizing otherwise ("you can bend the world to your will") it was always baffling to me how this guy could achieve this much. I'm probably missing something.
With all the wisdom that I have gathered in life, I can tell you that achievement- more often than not- is mostly the product of circumstances.
(That doesn't mean I believe in equal opportunities leading to equal outcomes.)
