Finding a niche, topic or category is ESSENTIAL for your blog. Otherwise, you’ll fail from day one. Believe me, I’ve mentored hundreds of beginner bloggers who all wanted to make it work, but failed since they didn’t choose a blog topic.
Here’s a simple rule I usually suggest: Choose a topic that you’re INTERESTED in. If you KNOW more about something than 99% of the rest of people, go with it. That way you can write about something that you’re passionate about.
If you don’t know what to blog about – don’t worry. You can still create a blog (you can figure it out later).
