Flow is being completely involved in an activity for its own sake. The ego falls away. Time flies. Every action, movement, and thought follows inevitably from the previous one, like playing jazz. Your whole being is involved, and you're using your skills to the utmost.

今天种下的每一棵树都是留给明天的遗产。

"The truth is rarely pure and never simple."

译文：进入山中不怕那伤人的老虎，只怕人世间两面三刀之人。赏析：世事难测，人心险恶，我们要防范身边那些口是心非，笑里藏刀，口蜜腹剑，阳奉阴违之人。

城市是一个共同的梦想。

民族的命运掌握在自己手中。
