GRAB YOUR PHONE
Moving tip: Take a photo of how your electronics before you disconnect them to be boxed up. Take a picture on your phone or camera of the cords on the back of your television and other electronics so that you can remember where they all go!
Before you unplug and pack up all electronics, label your cords. A piece of duct tape or masking tape, with the name of the corresponding equipment written in pen, will save you from having to guess what's what when you reassemble everything in your new home. This will save you a ton of time when you set it up again.
