Are self-help books a form of fantasy writing?

From Beth Blum, writing for Aeon Ideas: "Self-help is typically shelved in bookstores somewhere near the diet books and manuals of interior design. But a more appropriate location might be adjacent to 'Sword and Sorcery' or 'Sci-fi.' Some people like to imagine alternate worlds, and some are content daydreaming about an alternate life. Self-help is fantasy fiction for the earthbound. Like a good time-travel story, self-help books challenge the necessity of present circumstance. But while the alternate reality in sci-fi is typically the future, planet, or world, the only counterfactual in self-help is one's self."
