Are you stuck?
Are you facing a blank screen? Have you typed and deleted and typed and deleted and still you don’t like what you have? Try asking questions. Put yourself in the shoes of the reader and interview yourself. What are you trying to tell me? Why should I care? What do I need to know? What do I need to do? How should I do it? When should I do it?
This little trick can be used when you are first getting started, as well as when you are moving along. You could even take this literally and write in a question/answer format.
Does that really work? It can be extremely effective because the reader knows exactly what to expect.
Is it hard to do? Generally, no. On the contrary, it can help focus your thinking.
Is it effective? Certainly, if you ask the right questions. It’s a very clear and uncluttered way to tell people exactly what you think they need to know.
