"I believe that studying alone is not enough to do a job like mine... you have to have a natural aptitude for it, meaning you need to possess a set of qualities that no training program can ever guarantee. Memory, intuition, observation skills, a certain amount of “thick skin,” dialectics, the ability to synthesize... and courage. Either you have all this or you don't. The rest you can learn along the way... obviously, that's my point of view."
