Start with a handful of broad gateways, each pointing to a few representative cards. As patterns emerge, add links to clusters and structure notes. Resist over-categorizing; prefer pathways. Your future searches will follow curiosity rather than wrestle dense filing schemas.
Create occasional cards that summarize a cluster and list key links, almost like guided tours. These notes do not replace originals; they orchestrate them. As projects shift, update summaries, preserving history while exposing new avenues that reward fresh exploration.
When indexing, add two-way see-also references for ambiguous terms. Example: habit formation might link to identity, environment design, and motivation. Future you benefits when alternative routes exist, reducing dead ends and revealing constructive tensions between overlapping ideas across domains.
