First think of this...you have two dimensions to your relationship with your world. One is the internal/vertical dimension, and the other is the external/horizontal dimension. The four domains of EQ fit perfectly into these two dimensions. 

The first two domains are self-awareness and self-management, and both of these are completely within your internal/vertical dimension. The second two domains are social awareness and relationship management, and these are both within your external/ horizontal dimension. And the sequence matters! Good self-awareness and self-management leads to good social awareness and relationship management. This is so important that I devoted a major portion of the Goodfinding book to understanding and improving your EQ.
