出自先秦《荀子·修身》。利益少，但是道义多，这样的事要做。在利与义之间要舍利而取义，强调的是一种修身原则。

Separate the processes of creation from improving. You can’t write and edit， or sculpt and polish， or make and analyze at the same time. If you do， the editor stops the creator. While you invent， don’t select. While you sketch， don’t inspect. While you write the first draft， don’t reflect. At the start， the creator mind must be unleashed from judgement.
