My therapist cares, I'd say, because she's been in pain and come through the pain, so she feels empathy. She finds meaning for her pain in being able to help resolve others'.

Also, don't you ever feel good when doing good for someone else? Just a natural human reflex...

And then there's always pride in a job well done.

And then there's the pleasure of watching someone develop, whether as a parent, teacher, mentor or therapist.

The work can be deeply fulfilling in a way in which folks with other types of jobs may not be familiar.
