Something I've discovered in this industry is that there is no such thing as one size fits all. What works while drafting one book, may not work for another. I've written some books completely out of order and had to piece them together. Others I've written linearly. The same goes for revision. Some books make me want to pull my hair out during revisions because I have to track so many things and keep lists to make sure there aren't inconsistencies anywhere. Other books go so smoothly during revisions that I get a little worried because I feel it should have been more difficult.
And even after the writing and revising stage, things still aren't one size fits all. What works for one author while promoting a new book may not work for another. I'm talking about the exact same efforts yielding very different results. So how do we know what to do? Honestly, I think it's all trial and error. We have to try new things and old things to see what will work for that particular book. Time consuming? Absolutely! Frustrating at times? Absolutely! Necessary? Absolutely! Well, unless you don't care if your books sell or not, but let's be honest. We ALL care. ;)
Have you ever experienced very different results from the same strategies?
