Letters are the biographer's gold mine; they reveal what official records conceal.
信件是传记作者的金矿；它们揭示了官方记录所隐藏的东西。
Great leadership is about creating more leaders, not more followers.
The only thing worth writing about is the human heart in conflict with itself.
The only thing that makes life possible is permanent, intolerable uncertainty; not knowing what comes next.
追求知识是一段永无止境的旅程，每一个发现都为新的问题打开了大门。
历史不仅仅是事实和日期；它是那些经历过的人的生活。
