About this book
In this memoir, written with frankness and humility, Mark Haertzen recounts his 60-year entrepreneurial journey. His most important entrepreneurial project, Rocket Man, serves as the main case study for his reflections and contemplations. The book details the company's 31-year development with vivid, and at times painful, descriptions of its growth—from a startup founded in a garage with a prototype machine to a global manufacturer and exporter of beverage distribution equipment, with products sold in 65 countries.
Subsequently, Mark talked about the company's bold and strategic transformation: to become a leading provider of mobile sales services in the stadium catering industry, selling beer and other beverages at 75 venues from Delaware to California. Rocket Man has appeared at nearly all major sporting events in the United States, including the Kentucky Derby (25 times), the Super Bowl (6 times), World Series, Daytona 500, NCAA quarterfinals, and the Ryder Cup.
Few memoirs tell the story of the risks and struggles involved in founding a business in such a raw and unreserved way, as well as the impact these experiences had on both the individual and their family. Mark not only describes his greatest successes but also writes about those painful failures and feelings of insecurity; it is precisely these experiences that helped him grow from an impulsive, intuition-driven “born entrepreneur” into a logical, data-driven business leader over the course of several decades of transformation.
Throughout the book, Haertzen distills his own experiences into what he calls “Rocket Wisdom” maxims, such as “Nothing grows from the ground that is fully mature in its entirety.” These maxims provide readers with practical lessons, emphasizing perseverance, flexibility, adaptability, and viewing failure as a tuition fee for future success.
He also discussed the important role that mentors, partners, friends, and family played in his achievements, further reinforcing his belief that "entrepreneurship is a team sport." The Stay Thirsty insightful views are both a tribute to entrepreneurial ambition and a call for people to embrace risks, take a bold leap, and write their own stories.
