Inboxes to capture fleeting notes

I capture fleeting notes into three inboxes:

1. I use the Drafts app to capture notes on the fly.
2. I use an analog diary and pen (currently, Pilot G-2 10) to journal.

These inboxes are drained regularly in different schedules because efficient inboxes are reliably drained. Fleeting notes in Drafts and my diary are reviewed to identify interesting writing prompts. These prompts are transferred to the Craft inbox, which serve as a writing inbox for transient notes that will eventually be processed into evergreens.
