"Books are the quietest and most constant of friends."

"History is not a linear path; it spirals, trapping us in its cycles until we confront its ghosts."

If you only do things where you know the answer in advance, your company goes away.

My work is about people more than anything else.

人们变得文明，不在于他们愿意相信的程度，而在于他们愿意怀疑的程度。

Never close your lips to those whom you have already opened your heart.
