I read 100 books last year and there were five books that changed my outlook of life in some significant aspect. The list here: https://mailchi.mp/8ff9bef428e2/want-to-know-someone-better-...

Of those five books, "In the Realm of Hungry Ghosts: Close Encounters with Addiction" by Gabor Mate changed me the most. I actually re-read portions of the book last night.
