"Change happens when citizens are informed, are engaged, are paying attention, are asking tough questions," 54-year-old Obama said at the University of Chicago.
"Asking tough questions of themselves not just of others. Not too comfortable with whatever dogmas that we all attach ourselves to. And you are learning the kind of critical thinking in this school that will allow you to become really good citizens. Use it," Obama said in his interaction with students of the Chicago Law School.
Obama's presidency is set to end on January 20, 2017, when the 45th president is expected to take office.
