I shared my notes from The Bootstrapper's Bible on Sources of Insight. The Bootstrapper's Bible, by Seth Godin is full of insights and actions for improving your effectiveness in starting businesses. Seth includes a rich set of rules and guidelines to help you avoid costly mistakes and to avoid throwing your time and energy down paths that will never work out. From mental models to metaphors, Seth provides a great set of prescriptive guidance for getting your game on. One of the biggest "ah has" for me was figuring out whether you're an entrepreneur or a freelancer in terms of your business mindset.
