The book is beautifully designed and easy to follow. I personally love colour coordinating things, so having the separate colours for each spouse's section was an added plus for me.
The questions in the guide were thought provoking and forced us both to think beyond the immediate future into what we wanted our 50s, 60s, 80s and 90s to look like. That brought some great discussion that we wouldn't have otherwise had.
I also appreciate the quick goal pages towards the end of the book, to be used frequently to reevaluate our progress, instead of having to go through the whole book again.
Note, it did take a long time to complete, like a few date nights, because we found we lost steam to go all the way through in one date - but that varies for each couple, I suppose, depending on how deep or tangential the discussions get. :)
Overall I am happy with the purchase and was glad I got a downloadable version to print and reuse again and again.
