I'd be interested in topics about how I could make a difference in my community. Volunteer work I could do without having to quit my job and leave the country.
I was so inspired by reading Linda's "Grandma's Letters from Africa," but that sort of life would never work for me and Steve. (He's extremely independent, but he does wear leg braces, so a life in Linda's African outback would be too extreme for us.)
Nevertheless, there are things we can do to help out locally -- and sometimes those needs get overlooked. I like Songbird's idea to help people learn to cook, as well as the devotional concepts.
I am totally amazed at how few young people know how to buy healthy foods and create healthy home-cooked meals.
A mission of training people on how to create healthy, affordable meals will also feed the soul, IMHO!
