If you don't have anything nice to say then don't say anything at all... right? While this advice may work for home life, as Kim Scott has seen first hand, it is a disaster when adopted by managers in the work place.
Scott earned her stripes as a highly successful manager at Google before moving to Apple where she developed a class on optimal management. Radical Candor draws directly on her experiences at these cutting edge companies to reveal a new approach to effective management that delivers huge success by inspiring teams to work better together by embracing fierce conversations.

Radical Candor is the sweet spot between managers who are obnoxiously aggressive on the one side and ruinously empathetic on the other. It is about providing guidance, which involves a mix of praise as well as criticism – delivered to produce better results and help your employees develop their skills and increase success.
Great bosses have a strong relationship with their employees, and Scott has identified three simple principles for building better relationships with your employees: make it personal, get stuff done, and understand why it matters.
