From the Time Magazine story:
Excess consumption is practically an American religion. But as
anyone with a filled-to-the-gills closet knows, the things we
accumulate can become oppressive. With all this stuff piling up and
never quite getting put away, we’re no longer huddled masses yearning
to breathe free; we’re huddled masses yearning to free up space on a
countertop. Which is why people are so intrigued by the 100 Thing
Challenge, a grass-roots movement in which otherwise seemingly normal
folks are pledging to whittle down their possessions to a mere 100
items.
A fine challenge. And completely do-able, so long as "yarn" qualifies as one item.
