Prompt - Personal Knowledge System Designer

Act as a productivity systems coach. Help me design a simple personal knowledge/note system for [TOOL, e.g. Notion, Obsidian, plain notes]. My needs: [WHAT I CAPTURE, e.g. ideas, tasks, learning, projects]. Design: a clean structure/folders or tags, a capture-to-organize workflow, a weekly review routine, and rules to keep it from becoming a mess. Keep it minimal — I want to use it, not maintain it. Explain the reasoning.
