Everybody has a cherished dream, a life-long ambition. But not everybody is ready to give eye-teeth for it(готов все отдать). Of course there are obstacles towards achieving your goal and sometimes it seems that you hit a dead-end(зайти в тупик) but it is necessary to work towards your dream(упорно работать над) and it will be fulfilled.(воплотиться в жизнь). But watch the prepositions with DREAM to dream OF- мечтать о to dream ABOUT-видеть во сне So, those who dream of becoming pilots and those who cherish a dream to become an ATC- don't give up.
