I am getting the itch to paint my house. Which if you know me you probably aren't reading any further because you have passed out. I don't paint.
But if the itch does stick around longer than 5 seconds then I am going to remember to use this idea from Living with Lindsay:
After she paints a room she puts the some of the leftover paint in jars and labels them. That way if there is ever a ding, scratch or hole that needs to be fixed she can easily use a sponge brush and her jar of paint to touch it up. No need to wrestle with the paint can and it is small enough you can store it just about anywhere.
