We should just thank each other for our time. For the rest of our lives.

What I learned in Guinea is that we are all responsible for the state of our world. The world - and the system by which we trade, share, cooperate and conflict - is clearly not working. We are only as strong as our weakest members. UNICEF is run at every level by strong, relentlessly energetic, deeply capable people who use that strength, energy and capability to help those who need it most: the weakest, most disadvantaged women and children of our world. All I can do now is help make people aware of what is happening, of what they are doing. That is all that I can do. For now.

My favourite pudding is a toss-up between cheesecake - proper, New York cheesecake - and apple crumble and custard. Custard is very important, or dark chocolate mousse. Tea: probably Earl Grey, splash of milk.

I fundamentally believe that in the moral balance of the human race, we right ourselves. If we feel like the ship's keel is off, we find a way to steer ourselves through the storm repeatedly.

I gave myself permission to care, because there are a lot of people in this world who are afraid of caring, or afraid of showing that they care because it's uncool. It's uncool to have passion. It's so much easier to lose when you've shown everyone how much you don't care if you win or lose. It's much harder to lose when you show that you care, but, you'll never win, unless you also stand to lose. Don't be afraid of your passion.

I think everyone should pursue their dreams. Whether you want to play football, act, sing, become a writer or whatever you have burning inside you as you’re growing up, you should pursue it.

With any role, you're extending yourself and acting out things that never happened to you.
