Maybe you need to look at the schedule and not judge whether you are On or Off schedule until every week's end. That way you won't be frustrated everyweek. Did you allow yourself any "catch up" time in your schedule?
I know when we did the Jane schedule, we had a "catch up" every 6 weeks or so. I used the time to "get ahead" when I knew life things would be taking time away from quilting....like garden planting time, holidays, vacations, family visits...etc..
