Rory's answer makes sense.
But I think it would really help to have clear and written rewards for job's done.
For example, if one of your goals was to do laundry and wash dishes 3 times a week,
you can create a list of fun thing's you like to do, and then just change which reward you get.
If you want to get really anal or organized, you can create a reward credit system.
One 1 paper, right all the tasks or jobs you want to get done in a week, and then rate how much effort they are, and assign credit points. Let's say, changing your car's oil is 20 points.
Then on the 2nd page, create a list of rewards, and how much each reward is.
Then on a 3rd page, write down what tasks you did each day, then calculate how many points you earned, then pick how you want to spend them or save them, and then keep track.
Just do what helps you get more done, and feel proud of that!
