Every day is mixed but analyze: should I have theme days? Map task types that need focus: admin, creative, meetings, deep work. Calculate: if dedicating days to single themes reduces switching, what's the productivity gain? Show me the theme structure: Monday = admin, Tuesday = creative, etc. Give me the theme system: assign these themes to these days. Include: whether theme days would reduce switching, how to structure themed days, and if specialization by day would help.
