I just wanted to pop in and say I've been working my way through this since it was posted. Great book! A bit hokey with supporting anecdotes as dorky and... anecdotal as I'd imagined. But overall, a great frame of reference for establishing change. The "rider, elephant, path" metaphor provides a practical sketch of how to start thinking about change.
I find myself thinking about "The Power of Habit", by Charles Duhigg, while reading this. I think it makes a great companion piece in understanding what we do and how to change it, on personal and group levels. Duhigg provided his own guide to changing habits (
http://charlesduhigg.com/how-habits-work/), but I found it difficult to properly analyze my cues/routines/rewards in some instances. (For a small example, I've always chewed my nails. I haven't quite cracked the habit-cycle for that, but the exercise of looking for "bright spots" when I don't bite my nails has decreased overall frequency.) The Heath brother's book adds in the practical aspect of trying to get results even if you're not sure what the process behind success is.
