I’ve divided this book into two parts: Theory and Tactics. The Theory section will cover all sides of parallel entrepreneurship and lean on both my experiences and those of others who have also ventured into parallel entrepreneurship. I lay out a framework and incorporate insights and patterns from dozens of parallel entrepreneurs, so that we can understand the rationale behind splitting your time across multiple ventures instead of focusing on just one. This is important because we’ve all heard the refrain, “Focus, focus, focus.” I’ll explain why this is right (each business you start should be singularly focused) and why this is wrong (because—and this is the point of the book—you can have multiple singularly focused businesses!) The Tactics section covers everything you need to know in order to plan, build, and run a business on the internet—all while keeping your day job.
