If you're not the sort who gets on with a list you'll maybe have to try another strategy, but I love a list. I make it achievable and not too extensive, as I don't want to risk getting overwhelmed and not being able to tackle any of it. I write To Do: at the top, which is my being told (it was easier when I was in work and HAD to do stuff) and then a few easy tasks interspersed with things I mustn't forget. So it looks like this:
Vac living room [delayed if the cat is sleeping in there]
Post letter/card for X [a nice one as the postbox isn't far and good change of scene and fresh air]
Clean out cat tray
Take out chicken fillets to defrost
Change Boy's bedding
Colours wash
Phone opticians
Wipe banister rail [how does it get so mucky?! We do wash our hands!
]
I tick them off as I've done them, and if I do another job like watering the plants while I'm waiting for the kettle to boil, I'll add "Water plants" and a tick, as it makes the list look like I'm getting loads of shizz done and that's a positive 
I also do something, then sit down and MN for a little while, then get up and do another job. So it's like a reward for doing the task. It's easier to fit in around making yet more tea and going to the loo, as to do those I'd be on my feet anyway.
I don't do this every day, just on the days I need more motivation. It's strangely satisfying to see a list of tasks all done with ticks and know that I have achieved something with my day...
