An interesting article, Leonard. I am sure it must have been a surprise that most of your writing does fall into a niche after all. A lot of mine is poetry, but I do mix it up with a few articles, and short stories. To try and teach myself to write about virtually anything I started a series where I invited readers to submit ideas or titles for poems and I would write a poem matching each suggestion. This was challenging but also fun and I learned a lot. I am glad you are pushing yourself to write outside your comfort zone. I think that is important for all writers.
