I admire him because Leonardo's genius is evident from the many fields he has mastered. He is a painter, sculptor, inventor, researcher, engineer, anatomist, mathematician, plant and animal expert, optician, aerodynamic, and even a capable musician. He learns without limits. Of course this is not hard because he does not work hard, he just "have fun". To paint humans, he specifically studied the anatomy of the human body. Leonardo is probably the craziest learner. While studying anatomy, he likes to go out at night, dismantle the grave, and pick up the corpses of unfamiliar people who are almost rotten and dissect them. Sometimes he did it in the hospital that gave him permission. He really wants to know why the human body is shaped like that. That way, he can be more detail in making his paintings.
