Step 3: Don’t Write a Big Book
To print a title and author name on the spine of a book, you need about 100 pages or so. This equates to around 10,000-12,000 words. My aim too was to write a book that could be read in a single commute or sitting on an eReader or smartphone.
Great advice in the above tip.
In our bright new digital publishing era, you don't need to write big books. Stay small, and publish faster.
