Peter Garrett opens with autobiography: hired into property development in his 30s with almost no relevant experience, sitting in a barrister's chambers on day two, expected to instruct on a high-stakes planning appeal. From navigating that uncertainty, he develops the Container Development Model, a framework for understanding how individuals, teams, and organisations grow. Three phases emerge: *realising yourself* (private exploration and learning), *showing up* (visibly taking a position before others), and *occupying the ground* (sustained, everyday accountability). Each transition requires breaking through a psychological barrier. The skiing analogy captures it: going down a steep slope, you must lean forward into the speed, not back; "scary stuff" that requires adventurous courage, not just technique. Garrett notes that many people pretend to occupy the ground when they're still showing up, becoming "particularly sensitive to any lack of acknowledgement." The model provides a coaching framework for recognising where someone is developmentally and helping them move forward.
