No More Mr. Nice Guy

This was one of the mos cringe-inducing books I have read. I was trying to sift through the BS to find some kernels of useful advice, and couldn't really.
For a while I thought it might be that it is out of date, but nope, at no point in contemporary history this stands to be a proper book.
And like many self-help books it can be summarized in 10 or so pages, if you remove all repetitions (like full sentences repeated, not even same idea in different forms).

Finishing this was an exercise in self-control and persistence.
