It’s important to write about what you know and love. This can be tough at first, as jobs tend to be few but as you gain momentum begin narrowing down the list of topics you find easy or enjoy freelance writing about.
Take stock of your background. Make a list of topics that are similar to your education or experience. Check each off the list until your left with 3-5 that seriously interest you. Remember, as you complete projects for clients you’ll begin to be associated with a certain area of expertise. Ensure this is something you can write about for years to come.
Don’t feel like you must limit yourself to similar niches. If you have a degree in psychology but also enjoy fashion as a hobby, write about both and anything else that seriously interests you as long as you're not overwhelmed. However, the more you already know about a subject, the less you’ll have to research and learn in the future. As we've discussed before, profiting from freelance writing is all about time management.
