Since everyone else is sharing their experiences with this book here is mine:
Reading this books was a huge turning point for me as someone with diagnosed mild Autism. I think a lot of the things in this books are fairly obvious to non neuro-divergent folks. But for me, it was like a manual on how to handle myself in social situations, a thing that was mysterious and frustrating to me before. I wouldn't say I am now some sort of socialite, but I am far from the days of being being excluded from basically every social group I attempted to be part of.
