I never thought that getting too caught up in someone else's situation would be a problem for me. Interesting to me to see that it seems to be a common thought.
I find it interesting why people do or do not choose certain careers. I find it interesting when those people (the two I pay and having read some others of their ilk) say they decided to do it because they care and wanted to help people. I still can't fully figure out how what they do is helping or caring. This is NOT meant to be mean at them - I am truly baffled. I can see it as a career choice because it is indoors, sitting, great autonomy (if working for one's self - not in an agency), the ability to deflect all criticism back onto the person who hires you, not much math, and one is not much bothered by staying still while people whine on or tell about really horrible things and nodding every so often.
