As quoted on BorisWatch, from an interview with Kirsty Wark:
It’s a bit like building an Early Learning Centre climbing frame. Have you ever built an Early Learning Centre climbing frame, Kirsty? If you ever build one, you’ll find that if you think about it too much, it all goes wrong. When you call the Early Learning Centre climbing frame suicide line, they tell you to just keeping going and not think about it too much. I found that advice very useful.
