This book goes against the common thinking that you have to build the next big web app, receive millions of dollars in funding, and then get bought out by Google. Instead of an all-or-nothing approach, Rob describes from his real-world experiences how a portfolio of niche software products and websites added up can allow you to make a great living doing what you love. As developers, many ways of how we think are challenged, but make sense when focusing on profit and freeing up time. Emphasize marketing before product development. Test a market before investing too much on building. Outsource to virtual assistants and possibly other developers. Rob has around 10 products at any given time himself, each with their own unique situations on how they were built, bought and/or managed, and he uses them as case studies throughout the book. If you're like me you'll be taking tons of notes and referencing the myriad of links and resources it has as you start building out your software ideas.
