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.

我不是那种会让对努力的热爱减少的人。

最重要的是能够思考，能够观察，能够判断你所看到的事物。

Success is built on a foundation of failure.
