That is a great question. I don’t intentionally have any systems in place aside from keeping my book topics in a list. There could be some overlap with topics close in nature, but building on them differently.
For example, my book about writing books on Substack and writing books on Medium are very particular to those platforms, but have very similar information.
And then my new book, dogs a little deeper and builds on the things I did with the new things I’ve learned that work.
So I guess there could be a lot of different overlap in some ways. It’s far easier with my Christian Faith books because those are far more specific than my writing books.
