Let's back up and think about how anything you do works most efficiently when you have everything you need for the job right there at hand. When you bake, you don't walk into the bedroom for mixing bowls and out to the garage for flour. That would be silly. You keep everything in the kitchen, where it is right at hand.
But by the same token, when you open mail, you shouldn't have to walk around to find your letter opener, recycling bin or trash can. It all should be right there when you do this task! Even better, open your mail next to your files and bill payment station - all important records can go right in the drawers and bills can get set up for payment immediately.
So - where are you going to open your mail now that you know better?
