I have read part of Thinking Fast and Slow for school literature circles, and it has some very interesting points and lessons about thinking (e.g. overconfidence, heuristic bias).
Maybe it's because I had to read it for school, but I have a lot of difficulty getting through the book

. I felt like it repeated a lot of information, and it could have been much shorter.
Those are just my thoughts though! It's hard for me to get through nonfiction in general XD.
