Integration across domains

Connect what you know about work with what you know about relationships health and creativity. Domain boundaries are administrative conveniences, not real walls. The schemas you build in one area of life contain structural insights that transfer to every other area — but only if you deliberately practice moving knowledge across those boundaries. Integration across domains is what turns isolated expertise into a unified operating system for living.
