I hope you will judge yourselves not on your professional accomplishments alone, but also on how well you have addressed the world's deepest inequities…on how well you treated people a world away who have nothing in common with you but their humanity.
I prefer to supervise the whole operations of the government myself rather than entrust the public business to subordinates.
