I would seriously recommend this!
Get past the teeth gritting school teacher approach Anthea assumes in the first episodes and you'll begin to see the series for what it is, a highly motivating programme to help people who've lost their way, (or never found it), sort out their homes and put systems in place to keep them clean and tidy.
For people who haven't a clue where to start sorting out your house, this DVD is brilliant at showing you how to go about it.
The first Saturday after watching these, I took two large boxes to the charity shop, a car load to the tip, caught up with a month's worth of ironing, sorted out my wardrobes and learnt how to fold towels properly.
Buy the DVD's first to motivate you, if you want to buy the book, buy afterwards and use as an aide memoir.
