Harsh, but true in my experience.

I wrote a niche blog for several years. Why did I stop? Simply because hardly anyone was reading the blog!

At first, I was writing for myself and an audience was not important. But over time, I came to realise that, although the size of the audience was not important to me, the interest and engagement of readers did matter (especially for a blog with a very niche topic). Hardly any readers commented on my blog posts - which was important to me.

I don't regret writing the blog at all. Writing down my thoughts, experience or research all helped me better at writing.
