Paper Clutter

Do you often get paper clutter build up throughout the week?  I know I do.  Kids worksheets, mail, newspapers, etc.  I have to spend a good portion of time on it once a week.  I'm going to start working on a solution to this problem.  I want to go through it as soon as I receive it.  That way, it won't build up.  Have you come across any really good ways to cut back on paper clutter?
