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.
性格不是你与生俱来且无法改变的东西,比如你的指纹。它是你并非与生俱来且必须负责塑造的东西。
There is no such thing as failure. Failure is just life trying to move us in another direction.
