The lighthearted moments of 'Girls' are really not speckled throughout and that to me is just super exciting, to be able to delve into the darkness that you are greeted with in your early 20s and the fear and what that makes you do, the places that you can potentially go with that.

I started my own Pies Descalzos/Barefoot Foundation when I was 18. We provide education to vulnerable children in Colombia and other developing countries. I am an avid believer that education - and especially early childhood development - is the key to breaking the cycle of poverty.

My recurring nightmare is that someday I will be faced with a panel: Franklin Roosevelt, John Kennedy and Lyndon Johnson all of whom will be telling me everything I got wrong about them. I know that Johnson's out there saying, 'Why is it that what you wrote about the Kennedys is twice as long as the book you wrote about me?'
