Multi-Week DVD Programs...Any other serial starters? Advice?

I have owned XTF Max for at least 5 years now. It is a 13 week at home DVD series with a set calendar to follow. I LOVE the workouts! I work my butt off and I feel good after them, and they don’t take more than an hour. So WHYYYY have I not been able to make it past week 6 before giving up, ripping down the calendar, and vowing to try again when I “have the time” like I will ever have 13 weeks free just lying around haha. Does anyone else do this? Has anyone else overcome this?
