 For inner city kids, it's 1970, they're trying to give a break to the kids from the inner city. And I'm one of those kids. And I get to Northwestern, and suddenly my potential is realized. Suddenly I'm in these classrooms with these top-flight things and all this advanced philosophy and math and econ, and I'm ace at everything. And I just kind of break through. So in 1972, I go off to graduate school at MIT.
