In software development, rubber ducking is a method of debugging code, where you debug your code by explaining it, line for line, to a rubber duck. By describing what the code is supposed to do, and at the same time observere what the code actually does – discrepancies become apparent.
I suggest you use the same approach for creating high quality content. You get out your favourite rubber duck and start explaining what the topic is supposed to say, all while you’re reading the text. Any incongruities will become apparent. This approach helps you deliver higher quality content without even involving another person in the process, and is highly effective.
