There is none of Kennedy's “by the end of the decade” bravura about the announcements from Beijing.

来自北京的宣告缺乏肯尼迪的坚信“到这个代末”。（阿波罗11号在1969 720登陆球）。

Even when no one is listening (or reading, or watching) , every outing is a bravura performance, because you as the creator are happy. Perhaps even ecstatic.

便没有人听你演奏（或是读你的东西，看你的表演），每次出手都是一场炫技表演，因为你为创者会感到快乐，甚至是狂喜。
