Be fully prepared before you start writing. Once you start writing, you should stick to it in one breath and take out the first draft in the shortest time. This is the secret of many writers. Some people like to chew words repeatedly when writing articles, think about words while writing, and stop to look up words that can't be remembered in the dictionary for a long time. In this way, it is easy to interrupt the train of thought. In fact, the first draft might as well be a little thicker, with some flaws in materials or words, as long as it has nothing to do with the overall situation. Don't change it for the time being. It's not too late to deal with it after all the first drafts are written. This is what Lu Xun did.
