I used to be at inbox zero all the time by staying on top of unsubscribes, filtering, auto-categorizing.

Then I tried not caring and letting the inbox fill up.

I was surprised to learn that nothing really changed. I just spend far less time on it.

Basically come in once or twice a week, glance without clicking unless something looks “important”. Leave.

My inbox is full now and I don’t care!

I guess you could say it’s a form of low time / low care preference.
