This too made me smile again. 😅 Many of us have fallen into this trap, but not all of us admit that we have been deceived. Life is much more complicated than following 5 steps. And as you say, if something works for one person, it doesn't work for another. Not to mention that such books are often written by people who have not been able to cope with their own problems, but at least they have found a way to make money, in a word - fraudsters.
Maybe it all starts from the fact that people don't want to admit that they have a hard time in life. We all have it difficult to one degree or another, in one aspect or another, because life is not easy to begin with. But everyone keeps quiet about it, publishes books, lies to people, it's all a scam.
Since I started writing here about what's happening to me and how I feel (because I can't anywhere else), I don't know if it's helped me at all, but I think it would have been a lot worse if I didn't talk about it at all and I kept it all inside me.
I say this to encourage you to write further 😊
