I was between jobs a few years back and decided to try and give it a whirl at using my formal education to help others. Took a job as a grief counselor at a local cemetary. It actually ended up being a salesman for pre-need and at-need cemetary services. Worst thing is that is was full commission. While I loved helping folks at their time of need, I hated the fact that I was actually selling them something they didn't want right then but knew they had to have. I lasted about 3 months and knew I had to find some other way to use my experience.

My advice - plan ahead so you don't have to make such an important decision at the worst possible moment in your life for your loved ones.
