The FAQ of you
Answer the questions you're asked all the time
Today, make a list of the questions you get asked all the time, even the ones you dread and ones that make you roll your eyes. These could include questions you are asked professionally because people look to your expertise regularly, or questions about your life that seem to come up all the time.
Once you have your list to your satisfaction, pick one and write about the full answer and about how you feel about being asked. If that goes fine and you want to do another, go for it. Hell, answer the full list if you like.
Not only could this yield some great pieces of writing very much already in the space your readers have indicated that want to visit, but it can also be pared down and serve as a blog post or an actual FAQ on your website later.
