First Lady Michelle Obama waves to students as she exits Lane Stadium following the Virginia Tech commencement in Blacksburg, Va., May 11, 2012. During her commencement address Mrs. Obama said, “…in the end, people can only define you if you let them. In the end, it’s up to each of us to define ourselves. It’s up to each of us to invent our own future with the choices we make and the actions we take.” (Official White House Photo by Lawrence Jackson)
