时间不是线性的；它是一个循环。
"Time is not linear; it's a loop."
简单不是缺乏复杂，而是对复杂的解决。
善于学习的人，能够透彻地知道事情的道理；善于实践的人，能够把事情疑难之处弄清楚。
The old believe everything; the middle-aged suspect everything; the young know everything.
书籍是最安静、最恒久的朋友；它们是最易接近、最睿智的顾问，也是最耐心的老师。
The writer’s role is to question, not to comfort.
The challenge is to make the invisible visible.
Adventure should be 80 percent planning and 20 percent sheer guts.
