"If you tell me that there are obstacles in the way of your ambition that make it impossible to pursue, then I know it's not a real ambition. There are always obstacles. The 'perversity of events,' as someone once called it, is always ready to lick us. Events are never right for achieving what we most want to achieve. If this were not so, there would be no real fun in being 17 -- or even in being alive."
