When we talk about how improvisation works, we explain that it's like a pizza. Everyone gets to put a new topping on it, but it's all on the same crust.

Like any recruit, when we talk to them individually, we explain where they're going to fit in so they understand exactly what it is we expect of them, ... And when I recruit kids, the main thing is if they'll be a good fit to the program, and with these two that was an easy decision.

Every patient, when you talk to them, their goal is just to get out of the limelight. If this works, many potential patients who are on the fence will change their minds. But if this thing crashes and burns, it will damage the field.

I have heard of many occasions when academics rely on children to explain why a game works and then rely on their own area of specialisation to analyse the game.

Sometimes it works, sometimes it fails, but that's what we face when we're dealing with improvisation.

It's hard to explain if you haven't been through it, but even when we were down, we just had the type of feeling that only we can have.
