The 7 Habits are principles that help people to be leaders of themselves and others. You can think of these 7 Habits like a tree. The first form the roots of the tree, and only you can change them. If you try to change other people before changing yourself, it wont work. All change starts with you It's an inside-out approach.
The next three habits form the trunk of the and branches of the tree. These habits deal with getting along with other people.
Above the tree are things that nurture the tree, like rain and sunshine. Habit 7 is the habit of renewal. It breathes life into all the other habits.
