I think this is the point though right? The author is saying that he rejects this dichotomy and he's attempting to take on both even if others might perceive it as impossible.
What the author is at risk of doing, in my opinion, is pretending to a certain extent that he can have his cake and eat it too. As I wrote in my original comment, "you can't have it all."
Please don't take this to mean that you have to choose between your family and career (or a business). That's not what I'm saying. What I'm saying is that, at a certain point of "ambition", there is no perfect balance possible between all the the things you're trying to maximize.
The wise person accepts that sometimes you have to make choices, and choices always require that you give something up to get something else.
Sometimes the rewards do not match the sacrifice/effort, but that doesn't mean you won't pick that same choice when given the chance, or that it was a "bad choice". If you accept what may come from your choices, you can more objectively act upon them.
