Well, here's a tinyurl link to Amazon, with "goal-setting" as the search term:

I think Barbara Sher's book WISHCRAFT is cited quite often, and just Google "setting goals" and you'll see the basic SMART framework pop up all over the place. After you've read about 4 or 5 of these articles in a row, you see the same things repeated: set measurable objectives, set deadlines, make sure the goal is achievable, etc. The basic concepts become the vocabulary other writers use when writing on the same topic.
The value to me of Forster's second book is that he doesn't focus on SMART to begin with; instead, he uses methods from Robert Fritz's book THE PATH OF LEAST RESISTANCE to help one create the initial vision of what you want to achieve. In Mark's latest newsletter, he does talk about the value of using measures to monitor where you are and where you're going, but it's not the focus of his second book, which I think is more about giving the reader some basic tools to get them started.
