I think this is a good book to read. Not everything in this book works for me but I can use some of the things mentioned in this book. The book teaches me how to have a good relationship with my friends, family, and co-workers.
As you know, habit, according to psychology, is a conditioned response to stimuli. This means that it can be learned through repetition or reinforcement. Unlike Pavlov's dogs, people are highly complex and dynamic and each reacting differently to the same or different situations.
According to Stephen Covey the 7 habits are:
1) be proactive,
2) begin with the end in mind,
3) put first thing first,
4) think win/win,
5) seek to understand, then to be understand,
7) sharpen the saw.
It has a high level of abstraction. Also, part of this book sounds more like philosophy or even religion, which will not sit well with everyone. It is also important to reread this book because it will talk to you in different ways at different stages in your life.
