Mark what clothing you haven't worn with hangers  You know the
golden rule of de-cluttering: If you haven't used it in 6-12
months, get rid of it. When it comes to the jungle that is your
wardrobe closet, productivity guy Merlin Mann suggests using
hangers to mark off what stuff you have actually worn over time.
First, turn the hangers of all your clothing away from you, and
set a calendar reminder to go off in 6 or 12 months. Then:  When
your n months have passed, and your calendar reminds you that
it's time, open your closet and remove every piece of clothing
on a backward hanger; the chances are good you can give it away
without the slightest pain, because you just clearly
demonstrated that you don't wear it.  Nothing like a classic
life hack that makes getting organized a mindless process to
start off the week.
