The article seems to be quite reductionist in it's approach. Like many things claiming to be "evidence-based". Most of such advice works quite well for people who don't need it. Especially for the people with low income, low social capital, poor health and low personal skills, much of the advice will be outright wrong. And for some accomplished ones, it will serve as an extra prod to shame the former: "Well of course they are not successful, they don't follow what scientists say." The question is: why don't they.
