The 10% Entrepreneur

Patrick J. McGinnis, himself a 10% entrepreneur, shows how to put a tenth of one's time and resources into startups while keeping a steady paycheck. Full-time entrepreneurship often means irregular hours, no job security and little pay. His step-by-step plan runs from choosing a first project to deciding how to commit resources to it, and favors projects that also make people better at their day jobs. Part-timers can act as founder, angel, adviser or aficionado. Profiles include Luke Holden, who started a lobster-roll business and ran much of its first year while working full time in corporate America, designer Dipali Patwa and her infant clothing line, and friends from a Bible study who started a brewery.

MailBird chief executive Andrea Loubier paired it with Girlboss as books that help people plan strategically and take the risks entrepreneurship requires. 500 Startups partner Marvin Liao included it in a reading list he shared in an interview.
