He has no problem throwing around million dollar numbers, but doesn't mention his businesses in this piece. He doesn't go into greater detail how they worked in those situations, which would help demonstrate the claim of universality of his advice. Though it could just be because he assumes his readers, the "Grinders," will already know this. But it could also be to encourage me to pay for access to his 'Truths.' Reading more through his site I get the impression that it involves affiliate marketing, and selling coaching/forum subscriptions to wantpreneurs.
His tone itself is weird, where he paternalistically identifies his readers as "Grinders," and behaves like a shaman with access to 'The Truth' which you will not be able to obtain from anyone from him.
In one article, he tries to deconstruct the idea of ROI, or he creates a strawman version of ROI, and focuses on a way that some people might misuse this number. It basically encourages people to ignore the numbers. He also keeps promising to be straight with the reader in a completely non-straight roundabout manner.
It seems to reject the idea of ROI, which is essentially an emotionless analytic tool, in favor of what doesn't conflict with someone who is selling you the entrepreneurial passion and packaging it as your personal epic journey. He does try to contextualize this as more than just in situations where people lose money, but I think it is reckless to discourage people from looking at the cold numbers of any venture.
If his message in the linked piece is simply to avoid splurging on ads, I think it's been said better by others. Taken to its full extent, it goes too far in the opposite direction by encouraging people to be risk averse and avoiding any type of debt instrument.
That said, he does seem to possess charisma and a potent style that draws people toward him.
