Patrick J. McGinnis's "The 10% Entrepreneur" explains the concept of pursuing entrepreneurial ventures alongside a full-time job. McGinnis argues that dedicating at least 10% of one's time and capital to side projects can lead to valuable skills development, personal fulfillment, and financial upside. The text explores different types of 10% entrepreneurs, such as angels, advisors, and founders, providing practical advice on resource management, identifying opportunities, conducting due diligence, and building a network of support. The book encourages readers to embrace risk, leverage their strengths, and view entrepreneurship as a dynamic and ongoing part of their lives.
