Writing is the process by which you realize that you do not understand what you are talking about. Of course, you can learn a lot about something without writing about it. However, writing about something complicated and hard to pin down acts as a test to see how well you understand it. When we approach our work as a stranger, we often discover how something that seems so simple in our heads is explained entirely wrong.
