This was a very interesting article. You guys have a lot of guts to do this and if this is giving you meaning, then kudos to you :) it must have been a tough choice to sell everything and move without looking back. I understand that as you move on with life, you will want change and different experiences that help you move forth, I face that challenge too and yes, going to a new place and volunteering does help, that's what I try to do. You are giving your own life more meaning by the choice you made. Kudos and good luck :)
