Before long, you see signs that the clutter bug is back. Mail, magazines, and an assortment of papers are scattered on tables, counters, and other surfaces. Your once-tidy closets are in disarray. The kitchen cabinets are so crammed, it’s hard to find the one thing you need, when you need it.

It’s time to channel that new home mindset, the one where you put everything in a logical place and don’t cling to the unnecessary.

Here are some tips to get and stay organized by separated the clutter from the keepers.

Do you need it? Are you keeping things “just in case”? A half-empty bottle of lotion, cleaner, or other item that has been sitting on a shelf somewhere for ages is taking up space. If “just in case” hasn’t used up the remainder by now, throw it out.

Also, remember that “want” and “need” are two distinctly different categories. You need to have a first aid kit on hand. You want to have an overstuffed supply of extras. Distinguish between want and need so that you avoid keeping things where the clutter quotient outweighs its value.

Does it function properly? Do you have something you’ve been holding on to, until you can get around to repairing it? This could be a pair of pants, a small appliance, a piece of furniture, or maybe chipped pottery. If you haven’t fixed it by now, you’ve been living quite nicely without it. Diagnosis: Clutter.

How sentimental is it? Quite likely, a large percentage of possessions you’re clinging to have sentimental value. Ask yourself how much sentiment you need. Your child’s first tooth is a keeper. All the ones that followed are not. Your college diploma is a keeper. Your participation certificate from the intramural soccer club is not. You don’t have to be ruthless (well, maybe a little). Just be realistic. Something with true sentimental value is worth having close at hand—displayed on a shelf, hanging on the wall, or among your valuables. If it’s not worth looking at on a regular basis, the sentimental value has depreciated considerably.

Once you’ve gone through the task of purging, organize what remains by storing it in a logical location, in proper containers (not cardboard), and with clear labels, so it’s easy to find when needed.

Before you toss out some of your things, determine if it can be donated to local charities, churches, schools, libraries, senior centers, or other groups.

As a rule of thumb, schedule a purge annually. Make it a part of your spring cleaning routine so you keep the clutter bug out of your home.
