What does it mean that the capture habit precedes all systems?

No productivity or thinking system works without a reliable capture reflex. The system is not the bottleneck — the habit that feeds it is.

Example: An engineering lead spends a weekend building an elaborate Notion workspace — databases for projects, reading lists, meeting notes, a personal CRM. Two months later, every database is empty. The architecture is pristine. The capture habit never formed. The system starved to death.

Try this: Choose one anchor moment from your existing routine — finishing your morning coffee, closing your laptop lid, stepping out of a meeting. Attach one capture behavior: 'After I [anchor], I will open my capture tool and write one thought.' Do this for five consecutive days. Do not organize what you capture. Do not build a system around it. Just prove the reflex works.
