I completely agree.There is no school that can help you control your emotions in investing because you are in a protected bubble. Learning to master panic during falls or, conversely, curbing FOMO, are skills you can only learn in the field and you will never be ready for every eventuality. I also read a similar book, I don't know if it's the same author, but it doesn't tell you that many rich people are rich because they found the right people to make their first money. In order to invest you have to have an adequate income or assets, otherwise it's a gamble, and like all gambles it's a bit of skill and a bit of luck.
