It's snowing and the day is grey. You can change the picture when you decide it's time to address your address.
Pick a small area in your home and think about how it might look with less there.
Is your desk full of unopened mail? Have you considered that maybe in that pile of paper is a refund check, a card from one of the members of your family that might brighten your day and chase away the gray?
Start with just one side of your desk. The left side and concentrate on seeing what's inside those envelopes. You might be pleasantly surprised.
Set up a file for something you have left alone for some time. It will give you satisfaction to know where that information is now stored.
Clearing out a little section of your space can prove to be enlightening. Go for it and your day will be that much better. Yes.
