If you're considering writing a niche book to support your business, here are some tips to consider:
- The niche market must be sizable enough that you'll enjoy sales. Sizable means that like Beyond the Iron, there are events that take place worldwide. So go narrow, but broad enough within that market to sell copies.
- Try not to date the material. A niche book's overall goal is to sell over the long term. You'll want the book to have a decent shelf life. So don't make it on something trendy that will pass.
- Don't look for instant gratification. Sales are not meant to come in one big tidal wave. Instead go into the development of the book with an eye on overall sales in the big picture, and those sales will likely accumulate over several years to make the project worthwhile.
