Mary Wollstonecraft Shelley said this quote

Youth, elastic and bright, disdains to be compelled. When conquered, from its very chains it forges implements for freedom; it alights from one baffled flight, only again to soar on untired wing towards some other aim. Previous defeat is made the bridge to pass the tide to another shore; and, if that break down, its fragments become stepping stones. It will feed upon despair, and call it a medicine which is to renovate its dying hopes.
