Books/articles like this is presenting a world view. I don’t think they think this is the only way we should view the world. But I guess they are preaching a way to view the world, and as any preacher does they try to convince you why this is a better way.
(Somewhere they did mention not all people have the luxury to practice this, but she did documented examples where people in less-than-ideal situation have it turned around and do what they love.)
Regarding self-help, she said
“There are other ways in which 168 Hours does not aim to be like many self-help or time-management books. I approach this not as a productivity guru, but as a journalist who is interested in how successful, happy people build their lives. I am particularly interested in how people who are not household names achieve the lives they want, and what we can learn from their best practices. There are plenty of books out there on Fortune 500 CEOs’ or celebrities’ tips for success. I’m more interested in the woman down the street who—without benefit of fame, outsized fortune, or a slew of personal assistants—is running a successful small business, marathons, and a large and happy household.”
