Brian Solis had a book to write, but doing the work proved impossible. He cleaned his garage, re-organized his library, everything except write that book.  

It wasn't writer's block, he's authored plenty of books...sorting through this problem lead Brian to shelve that book and start a new one examining how to get his life, attention and order back into his life. That book, from Wiley is called Life Scale and it's fantastic.
