The so-called knowing by heart means that when drafting the first draft, on the basis of the overall outline, before writing each part, you should think clearly and sort out what you want to write in your mind, instead of writing one sentence, thinking about it, having one sentence without the next, intermittently.

(2) in one go

Try not to stop writing, write a paper and do something unrelated to the paper. If you must stop, you'd better choose a suitable place.

(3) Follow the outline

Generally speaking, we should try our best to complete the first draft according to the outline and the arrangement of the outline.

(4) The first draft is longer than the final draft.

The first draft should be as full and comprehensive as possible. In this way, there is room for modification and compression when finalizing the draft.
