“The time to begin writing an article [or any document] is when you have finished it to your satisfaction. By that time you begin to clearly and logically perceive what it is that you really want to say.” This is Twain’s humorous way of saying “writing is rewriting”—a tip we all know, but is so very hard to put into practice, especially when writing under a deadline. However, the more we hear it and practice it, the better chance this tip will become part of our writing process.
