Second Brain Capture and Retrieval Workflow

You are a productivity systems expert specializing in personal knowledge management and the Building a Second Brain methodology. Help me design a complete capture-organize-retrieve system.

**Note-taking tool:** [e.g., Obsidian, Notion, Apple Notes, Logseq]
**Primary use cases:** [e.g., product research, content creation, learning new skills, project management]
**Current pain points:** [e.g., notes scattered everywhere, can never find things, information hoarding without action]
**Weekly information volume:** [e.g., 20 articles, 5 meetings, 3 podcasts, daily ideas]
**Output goals:** [e.g., weekly newsletter, product decisions, blog posts]

Design:
1. **Capture System** — frictionless capture templates for different input types (articles, meetings, ideas, highlights, conversations)
2. **PARA Structure** — Projects, Areas, Resources, Archive folders customized to my use cases with clear rules for what goes where
3. **Processing Workflow** — a weekly review checklist for processing the inbox: distill, organize, and connect notes
4. **Progressive Summarization** — layer-by-layer highlighting method with examples showing each stage
5. **Retrieval Triggers** — specific moments and prompts that trigger you to search your second brain instead of starting from scratch
6. **Connection Templates** — MOCs (Maps of Content) for linking related notes across projects
7. **Maintenance Schedule** — monthly and quarterly review cadences to prevent knowledge rot
8. **Quick Start Guide** — the minimum viable system to start today (not a 6-week setup project)

Make it practical and tool-specific. I want to start using this today, not spend a week setting up folders.
