Editorial Book Review:

By Gus Schock

Ken Polk opens Built on Purpose with a distinction that most business and self-help literature quietly avoids: purpose is not something you find, it is something you build, deliberately, for others. That reframe does considerable work. It shifts the question from the introspective (“what is my purpose?”) to the relational and constructive (“what am I building, and for whom?”), and it positions the entire book as a practical guide rather than an invitation to further contemplation.

Polk is the founder of Arlington Family Offices, a multifamily office focused on wealth preservation, and a CPA and CFP with more than twenty-five years of experience guiding founders, families, and organizations through the transition from financial success to enduring significance. He has watched enough wealth dissipate across generations and enough thriving enterprises lose their animating spirit to know that success and significance are genuinely not the same thing, and that confusing them is expensive.

The 3 Laws of Purpose that give the book its structure center on character as the foundation of legacy, shared purpose as the engine of longevity, and the recognition that how wealth is built shapes how it is held and inherited. These are not abstract principles: Polk draws on decades of working with families navigating real decisions about money, identity, and what they want to leave behind. The six stages of purposeful enterprise he traces, from survivability to sustainability, provide a framework for understanding where an organization or family currently sits and what the work of the next stage actually requires.

At 168 pages, the book is appropriately disciplined for its subject. For founders and family stewards who sense that the financial plan is complete but something essential is still missing, Polk offers a clear-eyed account of what that something is and how to build it.
