I think pressure is a good thing and it's good to be able to feel it and use it and experience the feeling of it and especially if you can get past it.

I'm not clumsy, I'm just accident prone.

The paparazzi were outside the theatre every single night, but we came up with a cunning ruse. I would wear the same outfit every time - a different T-shirt underneath, but I'd wear the same jacket and zip it up so they couldn't see what I was wearing underneath, and the same hat. So they could take pictures for six months, but it would look like the same day, so they became unpublishable. Which was hilarious, because there's nothing better than seeing paparazzi getting really frustrated.
