How do I practice shortest path?

The most direct way to practice shortest path is through a focused exercise: Pick two ideas in your knowledge system that seem unrelated — one from your professional domain, one from a personal interest. Write both down. Now try to connect them in as few intermediate concepts as possible. Write each intermediate concept as a node. If you get stuck, try a different intermediate. When you find a path, examine each link: does this connection suggest an insight you hadn't noticed before?

Common pitfall: Assuming the shortest path is the only path, or that it's necessarily the most important one. Shortest paths reveal the most direct connection — but alternate paths through different intermediate nodes can reveal richer, more surprising relationships. The shortest path is a starting point for discovery, not the final word.

This practice connects to Phase 18 (Knowledge Graphs) — building it as a repeatable habit compounds over time.
