Thinking is the hardest work there is, which is probably the reason why so few engage in it.
释义：不考虑在安逸的环境中要想到危难，用节俭来戒除奢侈，不使自己的道德处于深厚的境界，不能使自己的情欲战胜物质欲望，这就像砍伐树木的根却想要树木长得茂盛，堵塞水的源头却想要水流得长远一样荒谬。
一本书不仅仅是纸和墨水；它是活着的呼吸。
解释：礼仪和敬重是立身处世的基础。
If you're not failing occasionally, you're not pushing hard enough.
存心养性要谦抑专一，如春天般的舒缓温和；自察反省要谨慎严格，像秋天般冷峻严肃。
If you want to succeed, you must be willing to take risks and learn from failure.
