　　“Two gates there are for dreams," said Penelope to Odysseus after his ten years' wandering had ended. "One made for horn and one of for ivory. The dreams that pass through the carved ivory delude and bring us tales that turn to naught;those that can come through polished horn accomplish real things whenever seen."“梦想有两扇门，”在奥德修斯结束了十年的漂泊后，潘尼洛对他说，“一扇是号角制成，一扇是象牙制成。通过精雕细缕的象牙门得梦想不过是一场会归于无的海市蜃楼的童话;而那些通过磨砺的号角门的梦想才会成为真实，为人所见。”

　　Faith consists in believing when it is beyond the power of reason to believe. It is not enough that a thing be possible for it to be believed.当还缺乏产生信仰的足够理由时，要用信念去包涵。模棱两可不足以支持一个信仰。(伏尔泰)

　　Conviction is everything in wishing. If you don't believe in your own power to make your wish come true, your wish will fly away, never to be seen again. But which leads to the most important point of all. If you're wishing for something possible, then it may be possible for you to do whatever you need to make it come true. The ultimate magic is not wishing, but doing.在许愿时，必须要深信不疑。如果你不相信自己有能力让愿望成真，你的愿望就会飞走，再也看不见。但那正说明了最重要的一点。如果你所希望的是有可能实现得了的，那么你有可能会不惜一切地去实现它。最大的魔力不在于许愿，而在于去做。

　　As wishes may inspire dreams, so dreams may inspire wishes.正如心愿能够激发梦想，梦想也能够激发心愿。

　　If you would go up high, then use your own legs ! Do not let yourselves carried aloft; do not seat yourselves on other people's backs and heads. (F. W. Nietzsche, German Philosopher)　　如果你想走到高处, 就要使用自己的两条腿! 不要让别人把你抬到高处;不要坐在别人的背上和头上。(德国哲学家 尼采. F. W.)

　　It is at our mother's knee that we acquire our noblest and truest and highest, but there is seldom any money in them. ( Mark Twain, American writer )　　就是在我们母亲的膝上,我们获得了我们的最高尚、最真诚和最远大的理想,但是里面很少有任何金钱。(美国作家 马克·吐温)

　　Living without an aim is like sailing without a compass. (Alexander Dumas, Davy de La Pailleterie, French Writer)　　生活没有目标就像航海没有指南针。 (法国作家 大仲马. A.)
