I dunno, there's a lot of wisdom in books. The bigger issue as I see it is essentially that talk is cheap, and getting results takes action. The problem is when you read a self-help book you get a little dopamine boost which makes it feel like you're making progress when you aren't (at least not yet, not until you put the information into practice). I think a lot of people get stuck on these little micro-dopamine hits and never get beyond that.
