Life and work do not happen in separate boxes.
Your body affects your decisions.
Your relationships affect your work.
Your environment affects your energy.
Your technology affects your attention.
Your financial systems affect your freedom.
Most support handles one piece at a time. We work across edges, find the real point of leverage, and build practical systems where progress in one area strengthens the others.
