Do schools kill creativity?

When i started to hear Ken Robinson, i though "this guy is very funny" and i laugh with many of his jokes, but then i started to hear him carefully and i notice that he had many intelligent and different ideas about education. He advice us that the actual school system in many countries doesn't help children to be more creative and to found and develope their fortress in different areas. I agree with him that schools doesn't help children to face their mistakes and go on, they make them think that they have to be winners all the time. Our society use to think that people who has reach the top are more intellegent or they have a kind of gift, but they dont think that those people had to effort and commit mistakes to be where they are. When he was talking i remebered when i was on high school and i had to choose like 8 academic hours beside the obligatory subjects, i'm really thankfull of my school, because i could choosed whatever i wanted, in other school you have to choose bewteen a biology, math or humanist program. But in my situation i had different interest (as many architects), so i choosed 4 hours of art, 4 hours of math and 2 hours of psicology, that helped me to satisfy my different interest, that maybe were a little kind of weird for other people. But as Mr Ken Robison said, people had many kind of different intelligences.
Now that children spend more time at schools, its a good oportunity to rethink the actual education system, to give more oportunities to children to develop all their different intesert and kinds of intelligences.
