成功的关键是专注于目标，而不是障碍。

The first step in liquidating a people is to erase its memory. Destroy its books, its culture, its history.

The key is to set realistic customer expectations, and then not to just meet them, but to exceed them — preferably in unexpected and helpful ways.

——在广州全国青年联合会演说，1923年10月21日

人类最大的悲剧不是死亡，而是失去尊严。
