I think I would start over as a life coach or therapist / counselor. I don't want to prescribe medication or diagnose illnesses but I enjoy talking to people and helping them help themselves. I think a life coach would be more up my alley but you never know.
I enjoy what I do now but the idea of starting over and reinventing is exciting too. I also don't feel like what I do has as much of an impact on the community as I'd like it to. It is fun and that is important but it would be great to be able to do something fun and worthwhile for a change of pace.
