You don’t have to be an expert to write intelligently on any subject, but you do need enough knowledge to convince your reader that you know what you’re talking about. Spend some time thinking and researching before you sit down to write. What’s interesting, unique, important, or exciting about the subject? Why would someone want to read about it? Shift your imagination into high gear.
2. Write It Down
When you have some ideas to work with, start writing. Let your imagination run wild. Don’t worry about proper sentence structure at this point — just get your thoughts out in front of you and go with the flow. Ideas are like potato chips… if you have one, you’ll probably have lots more.
