Side Hustle by Chris Guillebeau provides a step-by-step guide for anyone looking to build a profitable side project without quitting their job.

You don't have to quit your day job to pursue your passion or earn extra money—side hustles can be created in your spare time.
Action trumps over-planning; starting small and iterating is more effective than waiting for the 'perfect' idea or moment.
Everyone has marketable skills or interests—success starts with identifying what you can offer and taking the first step.
