I know the debate between traditional/physical books and e-books is always evolving.
I also know that the passion to write is independent of books and their formatting. Allow this post to be your reminder to what it is you want to do! Formatting, page counts, they will always be there. That is the trouble of the work. It is just what we have to deal with. The quicker you get used to that, the easier your time writing will be and become.
What I will tell you as a cardinal rule is this:
If you want something quick, make an e-book.
If you want to say a lot more, do a BOTH (a physical book and a e-book).
Giving your readers options allows you as the writer to broaden your fan base, expose them to other stories you are working on, as well as builds the confidence you need (or will need) to continue writing the work you want. As a writer you must learn to cultivate as well as build. You do this when you master all tools at your disposal.
A good craftsman doesn’t ignore his tools–or how to reuse what has been overlooked.
