If you had to step over piles of clothes, papers and unidentifiable "stuff" just to get to your computer, you're not alone. Organizational guru Peter Walsh, host of TLC's hit show Clean Sweep, says millions of Americans are drowning in clutter.

Studies show that although families are smaller, homes are larger than ever. Even with more square feet of living space, many Americans still fill attics, basements and storage units with stuff. Peter blames overstuffed spaces on our super-size mentality. "We're in a culture that says more is better," he says. "We've been led to believe that things bring us happiness."

For more than 10 years, Peter has helped pack rats organize their homes and reclaim their lives. His techniques go well beyond color-coded boxes and plastic storage bins. Peter says he helps people uncover what's really going on underneath all that junk, which often leads to life-changing breakthroughs.

"[Stuff] robs people of so much," he says. "If your house is full of stuff, all the blessings that could fill your house can't get in. The stuff takes over. It robs you psychologically. You can't be at peace."

Don't distress over your mess—learn to conquer your clutter one room at a time.
