Waste of money?

So I have decided I am destined to miss most of my group personal training sessions. The Dandilion is too sick to take to Child Watch, so I will yet again be missing my Group Personal Training session. I alsready know I am going to miss next week, so that will mean making 2 of the first 6. Not getting much out of the workout if I can't manage to make it to class - and it isn't like I am getting any other workout time either. Spending the money was supposed to be the motivation to workout. I hope I make it to the last 2 classes.
