Ask HN: What books changed the way you think about almost everything?

Slightly off topic but I deeply wish I was half the man my library suggested.

Then again I've got no excuse not to be.

I went on to read more than a half dozen books by this author, all of them were equally amazing and thought-provoking. I wish I could like this entry times a thousand.

The Boy Crisis, Warren Farrell.

I discovered the dire situation of men, with health and social conditions that top women’s problems by a factor 50, but we’ve never heard about. Funny thing is the guy is still a feminist in his approach (give men what used to be only given to women), but finally seeing men in a society where we really carr a lot when women face a problem... it changed my vision of life and humanity.

OK, it might be a bit embarrassing to post this, but I'm going to say Marie Kondo's "The Life Changing Magic of Tidying Up."

Not so much for the tidying part (though I did find that extremely helpful), but the whole idea of only keeping things in your life that "spark joy" (not an exact translation by the way - "spark excitement" or "spark meaning" are other ways I like to think about it) has had a profound impact on me.

I realized there were lots of things in my life (much more than just physical objects) that I had just sort of accumulated without thinking about what I really like or if something was good for me. I found the benefit of "practicing" this concept without mundane household objects allowed me to have a stronger sense of what I really enjoy in the more important aspects of my life.

Ludwig Wittgenstein - mainly Philosophical Investigations, Blue and Brown Books, and On Certainty. It gradually changed how I view the entire world around me, and dissolved my interest in philosophy, as well as in many other "sciency" things that - I realized - I was only interested in because of implicit metaphysical interpretations that ultimately stemmed out of conceptual confusion.
