Ratan Tata : WaterSpeak in Naturenomics™5.0
What moves one very often is seeing a community that is almost decrepit because of lack of water. And then you bring in simple principles of conserving water and agriculture. After two or three years, you see that community suddenly becoming prosperous because they have fertile land. The whole community changes and, fairly soon, the members of that community will contribute to society. Nothing gives you greater pleasure than to see that transformation.
