I have done a lot of volunteering, both at home and abroad, and I highly recommend it. I always get more out of the experience than those I helped. Selfish, yes, but it just feels good. It's not always easy, but the greater the challenge, the bigger the payback.
Here are some published articles and blogs from the past that will take you deeper into the experience.
