Declutter, I'm serious here. The more stuff you have around the more it will clutter your mind as it clutters your living space. I know that for me this is very true. After a long break with the kids home and I don't have the time or energy to keep things cleaned up in the living area I am no where near as productive as I usually am. But once things are cleaned up and I've gotten things either put where they belong or I've gotten rid of things.
