The Courage to Be Disliked: The Japanese Phenomenon That Shows You How to Change Your Life and Achieve Real Happiness

I think Adlerism may not be entirely without merit, but there are certainly bits of it that I object to, including completely disregarding any past experiences you had ("trauma doesn't exist").

The book is barely readable, though. The dialogue is laughable, and the Youth character (the reader proxy) is violent, obnoxious, and generally annoying. He veers from aggressive levels of denseness and apparent stupidity to having genius-level insights and back so frequently and with such intensity that the reader gets dizzy.

Overall, the lack of nuance in the philosophy (not psychology) that's presented is so off-putting that I could barely finish the book, and would've given up nearly at the beginning had it not been recommended to me.
