The other key to developing this habit is to designate a space to sort your daily mail and paperwork. You should also keep a small garbage bin and shredder nearby to dispose of junk mail or items that you no longer need. Take 15 minutes to empty purses of receipts, go through your mail, empty backpacks, and throw out anything you no longer need. Whatever reward method you choose, you will need to do that immediately after finishing your 15-minute paper sort. Over time, this small daily routine will keep your home decluttered without any extra effort.
