At the Rice and Beans Banquet, Dr. Amadei told us about this site which contains tons of interesting videos relating to the Engineering for Developing Communities program at Colorado University.
Dr. Amadei used many statistics to describe the plight of the world but he reminded us that every number had a person attached to it. Paraphrasing Ghandi, he challenged us to be the instruments of change that we wish to see in the world. He reminded us that not all the worlds problems were technical. If they were, he said, we would have solved them already.
Most of the problems we face are soft problems; problems that are solved with communication, compassion, and understanding. Of course, we also solve problems with bricks and mortar and electricity, but that is not the true beauty of Engineers Without Borders, or the secret to its success.
Don't just make stuff. Make a 
difference .
