Though I am not actually employed and therefore do not make an actual income outside of social security, I believe that volunteering your time can improve your outlook. As I’ve written before, if your disability has left you in the position of no longer being employed, having a “mission” can be so uplifting.
One of my volunteer activities is to spend a few hours per week helping out at the farm where my service dog, Denim, is from. It’s an absolutely wonderful place right in Ipswich, MA. It is such a wonderful feeling being part of an organization that does so much good.
