This is a book to invite you to be more ambitious in your daily attempts to resolve problems or make decisions when you canŽt do so by yourself. Whenever you need the cooperation of others to obtain what you want or need, negotiation becomes the most effective tool and very often the shortest path to do it. The dichotomy is only theoretical, because, negotiating good, effectively, demands negotiating well, efficiently. The authors offer their intensive research, together with their teaching experience and extensive practice under a rich array of circumstances over the last thirty years in the field of negotiation. Like Ariadne in Crete, the reader who wishes to become an effective negotiator might find some efficient and effective clues to get what they need, and even more. Welcome to the journey!
