> PG has personally mentored hundreds, perhaps thousands of founders – whatever it is, a sufficiently huge sample size to identify some traits that correlate with founder success and happiness.

However, in this article the correlation only goes one way: He's not saying that most successful founders have these traits; he's saying that people with these traits can become successful founders. And the traits he talks about happen to perfectly match his own traits?

I'm sorry, but this reads very much like someone looking at their own past, not the result of an extensive, unbiased review of successful startup founders.
