Yeah. One of the distinguishing features of 7 Habits is how old it is. While I'm not familiar enough with the market to verify this claim, I believe it was the first of its kind.
As a result, most of the things it talks about are common parlance these days, because the people who read it 20 years ago have internalized it, remixed what they learned, mentored others, and otherwise disseminated its gems. That said, it remains on my list of books to generically recommend to anyone.
I'm not sure what "its kind" is, but self-help books go back a long way. Carnegie's "How to Win Friends and Influence People", recommended by PG, was written in 1936. "The Power of Positive Thinking" dates from 1952, etc.
But I certainly agree that 7 Habits is an excellent book.
I've actually never read either of those, which makes it hard for me to decide if they count as the same kind. If you think they do, that's enough for me. I amend my statement to merely indicate that it's really old.
