I was offered it at Christmas and I must say that at first I did not know how to take it ... Once alone, I began to leaf through it, and there's a total blast! - This is interactive and dynamic, it is not bored and goes away within - This is adapted to the person who reads it: I lent it to my friend, who did not fall on the same sheets as me - It is intelligent and full of references for those who wish to deepen - That he changed my life? Difficult to answer, I asked myself many questions, I learned things and I understand others; cheaper than psychoanalysis and interesting even for those who have not used a priori to challenge ... Brief amazed!
