First, Break All the Rules: What the World's Greatest Managers Do Differently - Tapa blanda

Great managers share one common trait: They do not hesitate to break virtually every rule held sacred by conventional wisdom. They do not believe that, with enough training, a person can achieve anything he sets his mind to. They do not try to help people overcome their weaknesses. They consistently disregard the golden rule. And, yes, they even play favorites. This amazing book explains why.
The frontline manager is the key to attracting and retaining talented employees. No matter how generous its pay or how renowned its training, the company that lacks great front-line managers will suffer. Buckingham and Coffman explain how the best managers select an employee for talent rather than for skills or experience; how they set expectations for him or her - they define the right outcomes rather than the right steps; how they motivate people - they build on each person's unique strengths rather than trying to fix his weaknesses; and, finally, how great managers develop people - they find the right fit for each person, not the next rung on the ladder.

Marcus Buckingham is a senior lecturer in Gallup's Leadership Institute.
