I discovered these when I was following Flylady. On facebook a group of women would sign in at the top of the hour and say what they'd do in the next hour then go do. Check back in 45mins later, have a break then do again at the top of the hour.
If you don't mind that other people are talking about housework that would be a free option for you?
I would be keen but with chronic illnesses I don't get much done each hour. 5-10 mins on a good day
Good luck with setting this up
