People with hoarding disorders have more trouble deciding what to keep and what to toss due to areas of their brains not functioning properly, finds a new study in the Journal of the American Medical Association.

Researchers asked 43 hoarders to look at photos of junk, and then choose whether to chuck them or not. After the researchers examined fMRI scans, they found that the areas in the hoarders' brains that help with determining relevance and importance were both over-stimulated when it came to deciding what to do with their belongings.

You might not have a basement overflowing with trash from the Reagan era, but you can probably stand to spiff up your workspace. (It's Friday--you're allowed to kill some time, right?) Here are four simple tips to silence your inner hoarder.

1. Get in the Zone
"The best way to get your office back on track is to establish certain zones within the room," says Peter Walsh, an organizer from TLC's Clean Sweep. All books belong on a bookshelf, all current projects belong in a vertical file organizer on top of your desk, and all past documents belong in folders stored in a filing cabinet. The reason you need designated storage areas is to assign limits; if your bookshelf fills up, it's time to purge, Walsh explains. Rather than buying a new shelf, sort through the old one and throw out the books you no longer need, he says.

2. Don't Make Your Office Your Museum
Adding personal flair to your office can make it feel more comfortable, but don't go overboard, says Walsh. What's acceptable? A few framed photos, your degree on the wall, an extra lamp, and a plant or two. That's it. The dozens of photos pinned to the wall, the 50-plus lanyards from past business trips, and the assortment of collector's mugs lining your shelf are excessive and need to go, says Walsh.

3. Take Control of Your Paperwork
Sorting through bills and receipts can be a total nightmare--but not if you have a plan. So start filing instead of piling, says Walsh. Have a ton of receipts lying around? Keep them on a banker's spike in chronological order, so when the end of the month rolls around, you can simply remove them and file them in a cardboard accordion file. The same goes for bills. But here's the catch: Once you've filled up a year's worth of folders and you haven't had to use any of those papers since you've stored them, chuck them out, says Walsh.

4. Keep Things Clear
Here's a stealth organization trick: Designate 10 minutes at the end of the day to clear and categorize anything that's made its way on to your desk since the morning, says Walsh. And keep flat surfaces clear. "The two largest flat surfaces [in your office] are your desktop and your floor," says Walsh. It's important to purge those areas of any unnecessary clutter, because in order to have a productive office, those spaces must be used for actual work, not storage, he says.
