Jay welcomes John Grimsmo of Grimsmo Knives for a wide-ranging conversation on leadership, manufacturing culture, lean systems, and the Six Types of Working Genius assessment. Fresh off implementing the framework with his family and team, John shares how understanding “working genius” helped relieve pressure, clarify leadership frustrations, and reshape the way he thinks about people, meetings, and workflow inside his company.


The conversation includes: why some people thrive in tenacity while others burn out, the surprising emotional impact of understanding your frustrations, how working genius creates a shared language across teams, the danger of over-optimization, and more.
