although sticking to one’s goal is key to success, sometimes one should be ready to give up. napoleon’s story is a case in point. after napoleon succeeded in seizing the crown of france, he should have been satisfied with his achievement. but he did not. he went on to conquer the whole europe. then after he succeeded in ruling almost the whole europe, he should have given up this ambition to expanding his empire. but he did not. he went on to invade russia and there he suffered a total defeat. later he was sent into exile and died in a lonely island.
