How do I practice note as knowledge node?

The most direct way to practice note as knowledge node is through a focused exercise: Open your primary note system. Pick 10 notes at random — not your best ones, just 10. For each note, write one sentence answering: 'What single idea does this note contain?' If you can't answer in one sentence, the note contains multiple potential nodes and needs splitting. If the sentence is vague ('some thoughts about leadership'), the note needs sharpening before it can function as a node. Score yourself: how many of your 10 notes are graph-ready right now?

Common pitfall: Treating your existing notes as already graph-ready without inspection. Most notes are too long, too vague, or too tangled to function as nodes. They contain three ideas mashed together, or they summarize a source without stating your own position, or they use language so context-dependent that you won't understand them in six months. The failure is assuming that having notes is the same as having nodes. It isn't. The transformation from note to node requires deliberate work.

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