And then there’s Shantell Steve, from my hometown of Chicago, Illinois. Even when bouncing from foster home to foster home in the toughest neighborhoods in the city, she managed to get a job at a local health care center, start a program to keep young people out of gangs, and she’s on track to graduate high school with honors and go on to college.And Jazmin, Andoni, and Shantell aren’t any different from any of you.

They chose to take responsibility for their lives, for their education, and set goals for themselves. And I expect all of you to do the same.
