Lead With Purpose is the field manual behind ST4Y READY. Written by retired USAF Chief Master Sergeant Darrius T. Smith after 28 years leading high-stakes teams, it turns technically strong managers into trusted, accountable leaders — and it works best when a whole cohort reads it together.
Individual copies, signed editions, and companion workbooks are available directly through the ST4Y READY Consulting bookstore.
