So I wen't ahead and picked a niche that was a very specific item of clothing as the guide said any niche can work. But now I'm in the second course and being asked to write more and more content and even articles now and I'm finding that I just don't really have any more to write on this specific topic.. What should I do, pick a new niche that isn't so specific a thing, or think of related topics and broaden what my site would cover? Any advice is welcome!
