Choose Markdown or similarly durable text, with human‑readable links and minimal proprietary syntax. Back up automatically to redundant locations. Should a vendor vanish, your notes remain intact and searchable, ready to migrate without drama while your thinking continues uninterrupted.
Use voice memos, quick mobile sheets, or inboxes to catch ideas wherever they land. Later, sit with them thoughtfully, rewriting in your words, linking, and adding context. This two‑stage flow preserves spontaneity while ensuring permanence emerges from deliberate synthesis, not hurried copying.
