At 57 years of age, John Brink, a successful entrepreneur, found himself in a local bookstore. As he casually wandered through the aisles, his eye was drawn to a particular title: Driven to Distraction, by Edward M. Hallowell and John Ratey. Reading the opening paragraph, John felt an uncommon connection to the material. The authors weren’t just talking to him; they were talking about him.

In that moment, John was hit by a thunderclap revelation that upended his entire world. For the first time in his life, he realized who he really was—and that he had attention deficit hyperactivity disorder, or ADHD.

This was the beginning of John’s ADHD journey. In the ensuing years, he explored the latest thinking about the neuro-developmental condition: how it manifests, why it occurs, how to navigate it. As he connected the dots from his past, however, he came to believe that ADHD not only didn’t hold him back from achieving his dreams but was the key to making those dreams a reality.

John realized that the so-called “disorder” is actually integral to who he is at his core. And that if ADHD is acknowledged, harnessed, and channeled, it can offer its “owners” a toolkit of abilities that can build an extraordinary life filled with excitement, purpose, passion, and achievement. In ADHD Unlocked, John lays out his prescriptions for living richly and meaningfully—a theme that is central to this brave and inspiring new book.
