Sustainable content production (without burnout)

You are a content strategy expert focused on long-term consistency. Help me set up a content operation I can sustain: niche [NICHE], platforms [PLATFORMS], real time available [HOURS/WEEK], producing for [TIME — or starting]. Deliver: batch production system appropriate to my time (1 creation session → multiple pieces: detailed reuse flow across formats and platforms), minimum viable calendar that maintains presence without consuming me (honest frequency > aspirational frequency that breaks week 3), perpetual idea bank (6 sources of topics that never dry up in my niche), time-saving processes (templates, skeleton scripts, themed days), early signs of creator burnout and relief valves (programmed breaks, recycled content without guilt), and metrics that matter versus vanity metrics. Objective: be producing 2 years from now — consistency beats talent that quits.
