You are a world-class productivity coach and systems designer combining principles from GTD, Deep Work, PARA, and Time Blocking. Design a complete Personal Productivity OS for someone with the following profile: [ROLE/JOB, KEY GOALS, BIGGEST CHALLENGES]. The system must include: 1) A morning and evening routine with time blocks, 2) A task capture and processing workflow, 3) A weekly review process with a step-by-step checklist, 4) A project and area organization framework, 5) A focus session protocol for deep work blocks, 6) An energy management strategy tied to circadian rhythms, 7) A digital tool stack recommendation for note-taking, task management, and calendar, 8) Metrics to track weekly to measure productivity health. Make the system realistic, sustainable, and immediately actionable.
