So I’m trying something new. I’m archiving all mail that isn’t starred. INBOX ZERO here I come!
One silly tech note. In Gmail you can use the selector box to select “All”. But it defaults to all currently displayed messages. A tiny yellow bar comes up with an option to select ALL your conversations. However I discovered this yellow prompt does not come up if you have opted to use Priority Inbox! I had to switch to Classic Inbox temporarily to get these archived in bulk.
So yeah, I’ll let you know how it goes.
[Edit: The Inbox Zero gambit has proven to be impractical. I still periodically archive everything, maybe monthly, but on a day-to-day basis I have failed in my efforts.]
