Hit Refresh (publisher: Harper Collins) is a book that is the blueprint Nadella has in mind as he tries to change the culture of Microsoft from know-it-all to learn-it-all. The new culture at Microsoft is all about listening, learning more and talking less. The book is a terrific study in changing culture. Nadella’s decision to launch Windows 10 in Kenya instead of Sydney was an effort to build a culture of inclusion. Both countries have educated and tech savvy customers as well as skill gaps. Building a culture that obsesses about the customer is not easy.

Have you ever wondered how to define talent? In ancient times the word talent was referred to as a measure of silver that was paid in exchange of someone's work. Better output by the person resulted in more payment - hence more "talent".We get fooled because we believe since we spend a lot of time with human beings we must be good at evaluating their talent and potential. There is a science of human behavior and a science to talent, just like there is science to astrophysics.
