Get cutthroat about spam mail
Just toss it. The furniture store coupons. The take-out menus. The credit card offers. The Internet company up-sells. The cruise ship fliers. You hold onto these things, thinking you’ll use them one day, and they just pile up and expire on your desk. You’ll be happier to throw them out and have a clutter-free space, than to hang onto 100 coupons in case you use one.
