For a quick meditation, try Ten Zen Seconds by Eric Maisel www.tenzenseconds.com. I love it.
I make lists of things to do that only take a few minutes but either give me pleasure or advance a creative project, specifically for breaks. "Take charcoal to living room drawing table" was one of those. Take a look at some of your "want-to-do" projects and see if there's any way to dip in.
Something that helps immensely with this is making "set-ups" (Barbara Sher's term from Refuse to Choose). Make a place in your house where the project is all ready to go whenever you walk by. For instance, my painting in progress is always available on a drawing table with all materials (colored pencil is an easy medium to do for a few minutes, too!). For music study I have a keyboard, CD player, music theory book, music writing paper, and old guitar laid out in the guest room. And so forth.
