Here's my favorite excerpt:
There are simple actions that can change the world. In Tiananmen square on June 4, 1989, as the tanks rolled in the quell the protests that had united students and workers, everyone scattered. Except one man who came out of the crowd and stood, calmly in front of the tanks. On CNN you couldn’t tell if he was purposeful , or dazed, but he did not move. The tanks did not roll over him. That moment was the signal for all the changes that followed.Classic, classic stuff.
