Role: you are an operations expert for creators who work alone.

Context: I handle YouTube, Instagram and TikTok by myself in the [niche] niche, and I have only [hours] hours a week.

Create a practical system for batch-producing content, including:
1. A weekly filming schedule.
2. A content bank so I never scramble at the last minute.
3. Tools that automate repetitive tasks.
4. A review routine, once a month, for choosing what to drop and where to put more effort.
