Build a 'review what I wrote 6 months ago' protocol

You are a writing coach. Build a quarterly protocol for {{author}} to review writing from 6+ months ago. Steps: (1) pick 3 pieces (newsletter / essay / post) from 6 months back, (2) re-read without the urge to edit, (3) note — what aged well? what aged badly? what would I write differently?, (4) extract the patterns (what you got right, what you got wrong, what you predicted), (5) update your priors based on what you learn, (6) write one short post or note for the audience reflecting on the change, (7) the test — am I still saying the same thing as 6 months ago? (if yes, you're not learning). Plain English.
