What draws me in is that a trip is a leap in the dark. It's like a metaphor for life. You set off from home, and in the classic travel book, you go to an unknown place. You discover a different world, and you discover yourself.

When I'm on stage, it's like a different world ... me connecting with the audience. It's a surreal experience.

Belfast during the Troubles looked like a different world.

The two impulses in travel are to get away from home, and the other is to pursue something - a landscape, people, an exotic place. Certainly finding a place that you like or discovering something unusual is a very sustaining thing in travel.

A sister is like yourself in a different movie, a movie that stars you in a different life.

You can be involved in media, and you can be involved in all the handbag hurling that goes along with it, and it's a different world.
