My favorite books on how to start a side hustle

Why am I passionate about this?

I studied economics and environmental policy but landed in entrepreneurship. I wrote The Parallel Entrepreneur after I sold my first company and continued to work on Rbucks, my blog, after I joined the next company. Outside of work I volunteer frequently in my community. I’m an Associate Professor in the Business Department at Diablo Valley College, where I teach marketing and sit on the advisory boards for both the Business and Computer Science departments. I also lead the Diablo Valley Tech Initiative (DVTI), an economic development organization incubated at DVC. Related to DVTI, I run Lamorinda Entrepreneurs, a community group that promotes and supports local entrepreneurship. I have a Master’s in Public Policy from the Harvard Kennedy School and a MBA from the MIT Sloan School of Management.

Book cover of The Parallel Entrepreneur: How to start and run B2B businesses while keeping your day job

What is my book about?

Building a product on the internet is relatively easy these days. It's the making money part that's hard. I wrote this book to help you become a parallel entrepreneur faster than I did, and to encourage you to do so while you have the safety net of a day job.

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. 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.

Book cover of Sam Walton, Made in America: My Story

Ryan Buckley Why did I love this book?

Sam Walton didn’t have a side hustle, but he was certainly a hustler. He fell in love with retail outsmarted his competition. It’s a fascinating read and takes the story of Walmart, one of America’s most successful companies and largest employers, all the way down to a competition between five and dime shops across the street from each other in a small town in Arkansas. If you think of each store as a stand-alone business (as Sam did), then Sam Walton was perhaps the most successful parallel entrepreneur in history.

What is this book about?

Meet a genuine American folk hero cut from the homespun cloth of America's heartland: Sam Walton, who parlayed a single dime store in a hardscrabble cotton town into Wal-Mart, the largest retailer in the world.  The undisputed merchant king of the late twentieth century, Sam never lost the common touch.  Here, finally, inimitable words.  Genuinely modest, but always sure if his ambitions and achievements.  Sam shares his thinking in a candid, straight-from-the-shoulder style.

In a story rich with anecdotes and the "rules of the road" of both Main Street and Wall Street, Sam Walton chronicles the inspiration, heart, and optimism…


Book cover of The Art of Profitability

Ryan Buckley Why did I love this book?

This book came by recommendation from Jonathan Siegel, the brains and brawn behind Xenon Partners, a private equity firm that I joined in 2018. This book summarizes several profit models presented by a fictional mentor coaching a business executive. It’s clever, poignant, and was helpful to me in thinking about other profitable business models. For example, in my side-hustle life, I use the Profit-Multiplier Model: running multiple small SaaS businesses in parallel using the same tech stack (make money off the same good or skill in different markets).

Along the way, Zhao goes through a number of business models and pushes his student to examine how a variety of businesses go about making money. Through Zhao's teachings, Steve begins to see how profits can be improved simply by taking a step back and gaining a new perspective.


Book cover of Russell Rules: 11 Lessons on Leadership From the Twentieth Century's Greatest Winner

Ryan Buckley Why did I love this book?

A great book about leadership and business. I pick it because it’s on the reading list suggested in The Art of Profitability. I learned that focus is important. Bill Russell was one of the greatest basketball players of all time because he worked harder and played smarter than everyone else. However, he also recognized that he doesn’t play every position. He needs to have a great team, one that adapts to the competition. He needs them all to play at his level and he was able to do that, winning the NBA Finals a record-breaking 11 seasons. One way to build a successful side hustle (or portfolio of side hustles) is to recruit a great team to help you.

Book cover of Skip the Line: The 10,000 Experiments Rule and Other Surprising Advice for Reaching Your Goals

Ryan Buckley Why did I love this book?

James Altucher has produced a gem. It is full of discrete shortcuts that anyone interested in finding success in business can apply to get where they’re going faster. I learned to brainstorm every day, to read often, and to work on ideas in parallel. I also appreciate that he recommends publishing early and often rather than overthinking and agonizing over every blog post and tweet. Just let it go, but have a plan, and be strategic. If that sounds contradictory, then you too should read the book. The beauty is in the nuance.

We live in a hierarchical world where experience has traditionally been the key to promotion. But that period is over! Straight, clear-cut career trajectories no longer exist. Industries disappear, job descriptions change, and people's interests and passions evolve. The key to riding this wave is to constantly be curious about what's next, to be comfortable with uncertainty so…
