What more is needed to be happy but friends, family, and enough to get by? Honestly, I think living in a culture with a strong sense of itself and its purpose is more important than any of the author's points, but people living in America wouldn't know what that feels like.
All of what makes America terrible and most of what makes it successful is the puritan ancestry of its institutions. More and more Americans are skipping having families. Why? Because it would interfere with their career. Translated: they want to work more. In an effort to work their way into heaven, they ignore heaven's gifts.
I know a lot of people that follow the author's advice, or try to (I can guess which cultural milieu this is coming from). They are all stressed out trying to save the world or something and nervous about failing (commandment number 3 is like saying "don't get cold in the winter").
