Moreover, this post is not about how to achieve "greatness". It is not even about reaching any sort of end state - it is merely describing a process that pg has said is correlated with good startup founders.
I think that the problem with your advice (which by the way also puts you in the category of "some guy on the Internet") is that "finding your own path" is even more vague and platitude-y. But again, I mostly agree with you. I am simply offering my own perspective on the concept of "relentless resourcefulness".
Thanks again for adding to the discussion.
