幸福不是一种权利；它是一种罕见而珍贵的例外。
Happiness is not a right; it is a rare and precious exception.
Sit down before fact as a little child, be prepared to give up every preconceived notion, follow humbly wherever and to whatever abysses nature leads, or you shall learn nothing.
成功不是幸福的关键。幸福才是成功的关键。
研究历史的人，贵在能够贯通古今的变化，探究天道与人事的关系。
