Grit

As with many books of this ilk, the thesis is more or less in the subtitle. I enjoyed the descriptions of the different seminal studies in psychology as they pertained to the topic, and I like and now often reiterate to myself “We do hard things”: but overall the book got really repetitive after the first chapter or two. Takeway: success is determined more by grit than raw talent. Perhaps as a self-identified gritty individual I was like... well, yeah.
