Query: An entrepreneur who teachs how to be a complete leader.

Living in a country which is the biggest coffee producer in the world, I do admire Howard Schultz because of his vision as an entrepreneur. It was impossible, fifteen years ago, to predict this tremendous chain of coffee stores in a country where we used to have problems to find an expresso to drink. The book tells a fascinating story of a man who is, simultaneously, a strategic, inspirational, coach and technical leader. His understanding of the importance of employee's commitment (and the reasons behind it) is a model for any manager.
