This was a much better book than I expected it to be. Sandberg is a very engaging writer with lots of personal anecdotes to ground and humanize otherwise abstract advice. The research is solid and there's lot of it, although it is nothing new or startling if you've been paying attention. However, the one big criticism of the book -- that Sandberg is speaking from a place of high privilege on how to succeed within the narrow boundaries of corporate leadership -- is absolutely true. It's a narrow definition of work and of success, and there's little in here of value if your career and goals are not at least on the same path as Sandberg's.
