I used to date a 'shrink'. She had a Doctorate, and a private psychotherapy practice. In contrast, i am an electrical engineer. She told me that it is nearly impossible to make a living [on this side of the pond anyway], without having the full Doctorate. A Bachelors or Masters in Psychology is nearly worthless [according to her]. In contrast, a Bachelors in engineering is quite salable. As to how to 'spice up' your application for graduate school, I really can't help much. Before putting in all that work, you might want to investigate what the career prospects for you will be, once you get the Doctorate. Best of Luck!!
