kind of a disappointing book, there is nothing new compared with other "genius finding"book, the author argued the importance of "deliberate practice", however with rather vague definition of the concept and its old-replicate application in individual development.
everyone knows the importance of mental toughness,feedback evaluation, and repeated, hard practice. the author simply reiterate without any innovative statement or breakthrough discovery.
if I have time, I would recommend another book called "outlier", after all, personal passion, the timing, the pure luck and 10000 hours rules seems more reasonable and convincing for success and greatness.
