My program director has a command of statistics that frightens me. He knows more about it than several psychologists who have had much more training in that area. He's aware of the intense mathematical computer applications out there.
He used his knowledge of that area to advance the area of predicting future violence in an individual.
I forgot the individual's name, but he has a master's degree in physics and has done some impressive research on TMS.
In my opinion, if you choose to only work 40 hours a week, you will have time to pursue other intellectual areas in this field without stretching yourself too thin. I think most people do not take a "unique" road because they get caught up in working more to make more $$$, or they get caught up in life (marriage, children, etc).
If you don't want to just do the daily clinical grind, I suggest you do a fellowship or get involved in research. You could also try to think of something unorthodox that utilizes your psychiatric training.
