Too much stuff can so easily accumulate and fill your apartment with unneeded items.  Apartment Therapy.com has a great list of items that you’ve probably already got too many of and how to pare down.

or three sets of sheets, at most, for each bed is plenty.  You can pass
those extra sets along to animal shelters or cut them into smaller
strips to use for rags.  Same with towels; do you really need a new one
each day?  Think about using a hair towel, a bath towel and a hand towel
for an entire week.  You can then donate those leftover towels to the
animal shelter along with your sheets!  Be sure to save a couple of
large towels to bring to the beach.

In the kitchen, chances are
you have too many glasses.  Unless you’re a bartender, you probably
don’t need a separate type of glass for every type of drink.  Consider
using stemless wine glasses you can use for everything.  Also, you
probably have a jillion tupperware containers.  Cull your collection and
only keep a few that actually have lids.  Throw the rest in the
recycling bin.  Or you can get rid of the plastic entirely and go for
ceramic or glass dishes that can go from oven to table to the
refrigerator.  Another option is to buy stretch-to-fit covers that
transform any bowl or plate into a container.

Cleaning and
grooming products can also accumulate.  Weed out the stuff you don’t use
everyday to make yourself pretty and donate the rest to a homeless
shelter or friends who might use it.  As for cleaning products, find one
all-purpose cleanser that will do all the jobs you need and toss the
rest.  Make-up is another place we can tend to hoard stuff.  If
something’s been around more than a year, it’s probably full of bacteria
AND you’ll probably never use it, so throw it away.
