把创作和改进的过程分开。你不能同时进行写作和编辑，不能同时雕刻和抛光，不能同时制作和分析。如果你这样做，编辑会阻止创造。当你发明时，不要选择。当你画草图时，不要检查。当你写第一稿时，不要反思。在开始的时候，创造者的头脑必须从评判中解放出来。
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.

The future of coal depends on balancing economic growth with environmental responsibility.
The only thing necessary for the triumph of evil is for good men to do nothing.
