"If you don't like the way the world is, you change it. You have an obligation to change it. You just do it one step at a time."
By the esteemed Marian Wright Edelman. If you are unfamiliar with her, you are doing a great disservice to yourself if you do not read about her as well as The Children's Defense Fund here.
I had the great privilege of working with the CDF last summer, and it was one of the most rewarding and worthwhile experiences of my life. Everyone I encountered cared so much for making a difference in the lives of children that it continues to motivate my work in graduate school today.
