Great read Tim! I think this is a valid point you make. Just because you have been successful at blogging, does not mean you will be successful at being an author.
As someone that wants to write a book myself, I think it will certainly be harder to achieve success as an author. Much like blogging, it’s a trial and error process. No one is an expert at the start, it takes a while to hone your abilities.
These are lessons I will take on board when I get ready to publish my book. Thanks!
