“En Harvard y otras universidades, estudiaron la importancia de la actitud en el éxito de las personas. Se descubrió que la actitud era mucho más importante que la inteligencia, la educación, el talento especial o la suerte. De hecho, se llegó a la conclusión de que hasta un 85% del éxito en la vida se debe a tener una actitud positiva y educable, mientras que sólo un 15% se debe a la capacidad.” 

“Several years ago Dr. Maxwell Maltz’s book, Psycho-Cybernetics, was one of the most popular books on the market. Dr. Maltz was a plastic surgeon who often took disfigured faces and made them more attractive. He observed that in every case, the patient’s self-image rose with his and her physical improvement. In addition to being a successful surgeon, Dr. Maltz was a great psychologist who understood human nature. A wealthy woman was greatly concerned about her son, and she came to Dr. Maltz for advice. She had hoped that the son would assume the family business following her husband’s death, but when the son came of age, he refused to assume that responsibility and chose to enter an entirely different field. She thought Dr. Maltz could help convince the boy that he was making a grave error. The doctor agreed to see him, and he probed into the reasons for the young man’s decision. The son explained, “I would have loved to take over the family business, but you don’t understand the relationship I had with my father. He was a driven man who came up the hard way. His objective was to teach me self-reliance, but he made a drastic mistake. He tried to teach me that principle in a negative way. He thought the best way to teach me self-reliance was to never encourage or praise me. He wanted me to be tough and independent. Every day we played catch in the yard. The object was for me to catch the ball ten straight times. I would catch that ball eight or nine times, but always on that tenth throw he would do everything possible to make me miss it. He would throw it on the ground or over my head but always so I had no chance of catching it.” The young man paused for a moment and then said, “He never let me catch the tenth ball—never! And I guess that’s why I have to get away from his business; I want to catch that tenth ball!”
