Since my early childhood had a strong fascination with politics and business. I was very appealed to know the story and motivation of the individuals who shaped the world in the past, the present and will do so in the future. I was a nerd always reading biographies and learning History when my classmates were chasing girls, playing football and getting drunk. I´m already in my forties but I am still fascinated with celebrities. What makes a big man big? It´s in the genes', in the family? In the school?, Or in the fortune? How much of success is due to sheer luck? How much is due to the will of power? Can we believe in fate? I got an MBA from Columbia University Graduate School of Business and a B.A. in Economics from Adelphi University. Since 1996, I have been an adjunct professor at Columbia University Graduate School of Business, where I teach courses on Business History. For over 10 years, I was a member of the Executive Advisory Board at Columbia Business School and Faculty member I have written many bestsellers on politicians, leaders, entertainers and celebrities. Writing and sharing my findings is the passion of my life. Thanks for reading my books. I hope you´ll learn by reading as much as I learned by writing them.
