I recently finished a highly mathematical theoretical physics MSc degree. My thesis was in string theory. The normal next step from now would be to do a PhD in the field.
However, I now see that all I wanted from this field was to satisfy my curiosity, but not necessarily to work in it. Also, if I could go back in time I would instead study psychology, and my "dream job" is actually to be a (clinical) psychologist. But now it is quite late to go back and start all over again with a Psychology BSc degree. 

The main characteristic of psychology practice that attracts me is the ability to look at the people you are helping in the eyes while doing so, and helping them in very personal ways.

So my question is: is there any job out there that mathematicians usually do that involve a similar kind and/or intensity of social interaction? I know this is a long shot, but had to ask.
