Mindtools has a summary of the book written by Steven Covey in 1990:  The Seven Habits of Highly Effective People.  First they recall the 3 distinct stages of personal growth:

• Dependence: This is where we start, dependent on other people. And without personal development, we would stay stuck at this stage. People who are dependent are inclined to deflect blame and shirk responsibility. “It’s not my fault!” or “You’re to blame!” are characteristics of this stage of development.  
• Independence: Through personal development, we become more independent and take responsibility for our actions. Still, however, we are not fully effective.
• Interdependence: At this stage, we develop the understanding that, although we are self-reliant, we still need other people to accomplish our goals. At the interdependence stage we realize that two heads can be much better than one, and we embrace the idea of working together for better results.

Stephen COVEY define an habit as the overlapping of Knowledge, Skills and Desire as shown below:

1. Be Proactive
