. . .you're going to find something that you've been avoiding dealing with.
After you finally deal with it. . .you're going to have to create a new file.
When you make a new label for the new file, you will realize you're out of label tape.

When you open up another drawer to get a new roll of label tape. . . you will find that you can't open the drawer because so many post-it notes are jammed inside.
When you pry open the drawer to take a closer look, you discover that most of the contents stored inside are useless and dated - yet sensitive - and need to be shredded.

When you turn on the shredder, you find that it is full-to-bursting.
When you empty the over-packed shredded paper into the compost bin, you see that the compost needs to be turned.
When you finish with the compost, you need to wash your hands.

When you wash your hands, you see that the foaming soap container needs to be refilled. . . . which reminds you that you have a coupon for soap refills.
When you open up the drawer to find the coupon. . .
And so it goes. That's how re-organization projects go for me! But. . . I perservered. Now my desk is organized, my sewing room is refreshed, AND my compost is turned!

Many thanks to Pam -- for pointing out the obvious: that home re-organization projects are Just Like If You Give a Mouse a Cookie!
