More personally, the relevance of this book to my beliefs and habits made me uneasy. After reading several chapters at a cerebral distance, I realized, "Wait, all this stuff applies to me too, and not flatteringly." In particular, thinking about what it means to stake worth on accomplishments instead of attributes, and to value performance instead of mastery, called into question the hypercompetitive scramble guiding me into and through our profession. Much of the research, when applied to myself, was downright scary, and led me to wonder deeply who I am, how I construe myself and the world, and what I hope for and suggest to my kids. Had I read this book at other times, especially during medical school, it might have trashed my sense of self. I expected it to be a pure thinking cap, but it was a blasting cap too. I doubt I am alone in this; let the reader beware.
