Most of my professional career was spent as a copy editor and proofreader.  Now, I'm in the middle of a career change--from publishing and marketing to the health care field.  In spite of the physical and emotional trials of working in health care, I also find a lot of personal satisfaction.  I finally feel like I'm doing something for the greater good.  Little is as spiritually rewarding as realizing you've touched another soul and helped make someone's life a little easier, even if only for a little while.
