Ask HN: What book changed your life in 2020?

I had a frustrating year with books, I read about 20% of the titles I wanted to, and only a few stood out:

* James Clear - 'Atomic Habits'

* Gabor Mate MD - 'When The Body Says No'

Both helped me kick some bad habits and start to undo years of self-inflicted mental/physical abuse.

How did you get on this year?
