The 90/10 Solution is the tentative title of my future best seller. Here you’ll find pages and posts which in a perfect life will end up in the book I’ve been writing my entire life. Anything you read here is a work in progress. Instead of future book content ending up buried somewhere amongst the archives of blog posts the book in progress lives here. I finally figured out how to create a menu with sub-pages on this blog. That didn’t take long.
