I agree with all of the above ! I've been using the "5-Travelling Folders" for a while now....
My only additional "two cents" that I have added is a 6th folder labelled "Return to Home"
You also may want to vary the names of the folders a bit - simply so they push better emotional buttons in you. For instance "Action Items" or "Action Support" can sound kind of clinical. Maybe a pun, or twist on that would be "Act-On Items?"
Stay in touch, and let us know how this all shakes out for you!
