Our lives are now in a telephone, all our data, all our finances, all our personal information, and so it's proper that we have some constraints on that. But it's not going to be 100 percent.

As tough as things have been, I am convinced you are tougher. I've seen your passion and I've seen your service. I've seen you engage and I've seen you turn out in record numbers.

I've seen a generation eager, impatient even, to step into the rushing waters of history and change its course.
