I do like Flylady says and do housework in 15 minute stretches.
She says when the timer goes off (in my case a loud alarm clock) then QUIT and go on to something else. In my case, the "something else" is always my computer till the alarm clock screams at me and then it's either slap the heck out of it or actually get up and do something else around the house.
Then back to the computer and this board.
