I think this is a case of the typical mind fallacy.[1] We generally assume that everyone else is as calm-neurotic/driven-lazy/straightforward-dishonest as we are. That's simply not the case. Genes, upbringing, and life experiences shape our minds differently. There are people who do nothing but work while being quite happy with their lives.[2] Some of us got lucky. Others, not so much.
That's not to say that people can't change. Even tiny alterations to everyday life can drastically affect one's happiness and/or productivity. Meeting a new friend, moving to a new place, or just being preoccupied with some new problem can completely change one's outlook.
So I agree with the author: Don't deny your faults.
But still try to fix them. They're not as immutable as you might think.
