Maybe that is the best lesson I learned in my first semester at Yale, because if I had gone to a less-demanding school and continued to sail along on the top, I am sure I would never have attained the subsequent achievements in my life.

In our culture, security has become an obsession.

And I've always said, 'If two people think the same thing about everything, one of them isn't necessary.' We need to be able to understand that if we're going to make real progress.

But, you know, we have these entrenched entities - and I'm talking about both Republicans and Democrats - who believe that when you're elected to office, you become some kind of member of the aristocracy, and that anyone who challenges you is attacking you and is unpatriotic. This is foolishness.

You know, I'm a physician. I like to diagnose things. And, you know, I've diagnosed some pretty, pretty significant issues that I think a lot of people resonate with.

There's absolutely no reason at all that physicians, scientists, shouldn't be involved in things that affect all of us.
