If you don't feel challenged, it's because you're not doing enough. Ballet should never feel comfortable. Comfortable is lazy! If you're comfortable when you dance, you're not pushing yourself hard enough. 100 % is not enough. You have to give 200%. One tendu takes years of hard work and will never be perfect. Everything in ballet is a challenge.
George BalanchineBallet dancing is arduous, strenuous activity. Students are engaged in physical training that rivals the training Olympic athletes undergo. At the same time, they strive for physical perfection not for the prowess alone but as a way of achieving the means necessary to express the pure nature of their art.
George BalanchineGod creates, I do not create. I assemble and I steal everywhere to do it - from what I see, from what the dancers can do, from what others do.
