It's sad that traditional education truly is the enemy of creativity. Basically, I think you have to be willing to let go of perfectionism, not to censor yourself, and BELIEVE in yourself.
I respectfully disagree, to me, at least American education is too "creative" to even be valid! They are way too much into "there is no wrong answer"/"everyone can be a star" [censored], and that ain't true creativity at all, it's a way to never study and still get As. Besides, I would rather see MORE pupils *pursue* perfectionism AND *censor* themselves, at least around teachers. I'm talking about public high schools.
What program are you in?
I definitely did not see "School of Rock," and I'm not sure about "Isn't She Great." It does sound extremely familiar, what was the plot?
