I can't tell you how many teacher PDs I've been to that have used the 7 habits and Covey's book. Some of my co-workers have walked out of those PDs. We teach in a very rough inner-city school and they don't think the book reflects the reality of what we face every day, and they have a pretty good point. Anyways, at least we got the book for free so I plan on reading it and changing myself from a Quadrant 1 kind of guy to a Quadrant 2 kind of guy.
