There are individual or collective situations in modern life that lead people to a dead end in terms of possibilities for change. The authors have analyzed the phenomenon and have been framed within a conceptual framework illustrated with examples from various walks of life that opens new avenues for better understanding of how individuals get caught in the meshes of their mutual problems and how they can help out of these labyrinths humans. The book describes two useful theories to shed light on fundamental aspects of change: group theory and the theory of logical and illogical sense of the changes. Who, according to a logical sense, has not had the frustrating experience of seeing that things went from bad to worse? And conversely, we have all experienced at some point, how did an illogical and surprising change in a blocked situation. Any global change requires other minor changes: the effect of the snowball that small changes lead to major changes. The authors, from the School of Palo Alto, much of the book devoted to the solution of problems: from specific areas, such as fear or isolation, the individual focus on the totality of life.
