Sometimes its the simple things that can help the most.  This happened to me recently.  I started writing down on a small piece of paper work that I wanted to get done around the house.  Then I cut 4 slits in each side (4 sides) making 5 tabs (20 total).  I then practice what I want (right now that's an etude I'm working on) and when done I fold down one of the tabs.  When all five are folded on a side.  I get up and do one of the chores.  Come back, do another 5 reps and then get another chore done.  My wife thinks its a really, really, really great idea.  Do you have any tricks that help you?
