10. Use a bulletin board for your wall:
You should have a place to organize all your bills and letters instead of putting them in a pile, and you'll have a hard time finding the invoice you want. Create a big bulletin board for you to handle things in an organized way. All you need to do is put a board on your wall and pin your papers on it. It will help you not to lose any bills or cards, save indoor space, and see everything when it's due.
