Think about this:
Author, speaker and creative guru, Sir Ken Robinson said this at this past year's TED Conference:
"Kids will take a chance. If they don't know, they'll have a go. They're not frightened of being wrong. Now, I don't mean to say that being wrong is the same thing as being creative, but what we do know is, if you're not prepared to be wrong, you'll never come up with anything original."
(Registration for the '07 conference is all but full, so check out previous excerpts of talks here.
