I am currently studying in fifth year in engineering school following a preparation in mathematics-physics (MP *). I had my scientific bac in Togo where I finished first of my country. These experiences taught me one thing: talent exists, but through work you can get to be talented. I am not even "talented" in math, but I am aware of the work and training necessary to be good in science and in any field with me. What I try to convey in my classes, more than science, are notions of work and training necessary to become good at science.
