Much faster processing
Yesterday I had my first weekly-review since I started implementing my work-by-routine-tray. I had a fairly big pile of stuff in my inbox to begin with, because I cleaned up a file closet just before the weekend, and many items went into my IB.
It took me an hour and a half to finish processing it, and only two items were quickly moved into my work-by-routine-tray, but processing an hour-and-half-thick inbox was so much easier for me because I knew that nothing is going to delay me in the middle.
Till now, since I knew that such items I don't like turning into projects because of the extra-overhead, and the urge to start-and-finish with them, so I do them in the middle of processing, there was resistance to processing. And it amazed me how easily it just disappeared!
I saw the bottom of my inbox this week so many times! Great.
