Range

Investigative reporter David Epstein’s 2nd book is an essential companion and counter point to Peak by Anders Ericcson and pop science books such as Outliers by Malcom Gladwell and Bounce by Matthew Syed.  If your interested in performance, decision making or education in any context this is essential reading.  If your performance domain is complex and ambiguous then specialization can be a problem and the benefits of generalization (Range) become critical.  Compelling and well illustrated.
