Your inbox should be like the lobby of the emergency room—that's where you do your triage.
At this point, very little goes into my inbox to begin with, and most of what does is important.
Consider it a personal philosophy — if someone takes the time to email me, I'm going to respond. It might not seem to give much value, but it actually makes me and my personal brand look better. Do you want to appear like a douche by not even deigning to respond?
Archive+next using the ] shortcut is a very fast way to plow through one message. Maybe 100 ms. Because it takes only a single keystroke.
But "Filter messages like these" takes several clicks and at least 10 seconds (maybe more) for intermediate pages to load. The filter is usually correct. How can I do that?
