Over the last couple of years, I've made four small loans of $25 each to people in developing countries. I admit that's not much but I've helped buy a goat herd, helped someone get an education and helped people start a business. It's not charity. The loans have all been paid back and I've learned a lot. You may not get rich but what a good feeling!
It only takes about ten minutes to sign up and find someone to invest in. Give it a try. http://www.kiva.org/invitedby/chris6015
