The human being cannot live in a condition of emptiness for very long: if he is not growing toward something, he does not merely stagnate; the pent-up potentialities turn into morbidity and despair, and eventually into destructive activities.

失败并不可怕，可怕的是不敢尝试。

未来是创造一个持续学习的文化。

无论是个人还是国家，只要生活节俭，就会繁荣昌盛；如果贪图享受，放纵欲望，那就会走向衰亡。
