He closes with a paragraph that could have been lifted directly out of MJWTI:
What is it like where you work? Does your company reward the best employees, or the best at self-promotion? Is Donald Trump really a good businessman, or just a good self-promoter? Is there even a difference between the two?
I’d say that, as an entrepreneur, the answer is (at least in part) "no". If you can’t promote it, (in most cases) you can’t sell it. And if it doesn’t sell, it’s not valuable.
