“Life is, by nature, highly interdependent. To try to achieve maximum effectiveness through independence is like trying to play tennis with a golf club – the tool is not suited to the reality.

Interdependence is a far more mature, more advanced concept. If I am physically interdependent, I am self-reliant and capable, but I also realize that you and I working together can accomplish far more than, even at my best, I could accomplish alone. If I am emotionally interdependent, I derive a great sense of worth within myself, but I also recognize the need for love, for giving, and for receiving love from others. If I am intellectually interdependent, I realize that I need the best thinking of other people to join with my own.”
