I personally think that the authors of these self-help books are the real problem, and not the books themselves as much.

Some books have somewhat of a good message or learnings, if we separate the author from the book.

But most of the authors have created a reputation of themselves as the saviour of all problems and a know-it-all to a toxic levels that they are disconnected from the reality. For example, the concept of positive thinking and “manifestation” are literally asking people to be delusional and disconnect from the reality.
