Grab a paper sack and see how fast you can fill it up with recycling.
Old newspapers, magazines, junk mail that didn't get properly processed when you carried it in, out-of-date coupons, sure, knock out the easy stuff.
But flex some real muscle and effect some real change in your file drawers by also purging user manuals for devices you no longer own, utility bills from 1998, and similar dead documents. (Don't forget to shred papers with personal information on them).
Get online and switch one bill over to electronic billing or pick up the phone and cancel one of those magazines or catalogs that helped fill your bag.
Now carry that bag out and put it in the bin. Hooray!
