Creativity and Dance in education

I have just come across the Ken Robinson's video Verity has posted and it has led me to further thoughts.
He Said ' If you're not prepared to be wrong, you'll never come up with anything original'.
This really opened up my eyes i am currently exploring ways to develop my teaching and choreographic styles and am struggling with new and stimulating techniques, and I think this is because I'm afraid to be unsuccessful and something not work. I am so used to the way I teach and the fact that it seems to work that I'm afraid of the unknown. So Ive set myself the task of the next class I teach I will explore new methods and note the outcomes- what worked and what didn't.

Another quote was 'In Every country in the world, the arts are at the bottom of the list, why do we not teach dance every day like we teach maths?'
Why is this? Is it simply because subjects like maths are deemed more important in every day life? I came to think of when I started dancing, it was my mum who noticed that I needed to be active and dance was what inspired me and I was lucky enough to go to a school that encouraged the arts. Should education be nurturing children's creativity further and opening doors in whatever genre it may be?
