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.

The truth is you don't know what is going to happen tomorrow. Life is a crazy ride, and nothing is guaranteed.

人生苦短，开心就好。

技术应该服务于人，而不是反过来。

作家的职责是照亮人类灵魂的阴影。
