Want to minimize the pile of mail you get? Try the PaperKarma app.
This app helps you control clutter in two ways:
1) It reduces the amount of mail you get.
2) It helps you avoid the temptation to shop by unsubscribing you from catalogs.
With your phone, just snap a photo of the address label of the catalog or mail solicitation that you want to unsubscribe from, and PaperKarma notifies the company and takes you off the mailing list.
It may seem fun to browse through catalogs, but constantly being confronted with the newest products is highly tempting and can create a sense of anxiety and dissatisfaction with the things you currently own. You can always look at that stuff online if you really need to shop for something. Letting the catalogs go will help restore peace.
There's a small fee for using the app (I believe after a certain number of free unsubscribes), but it's well worth it to help you get the influx of papers under control.
