I was at university and it was pretty easy, trundling along towards getting a job after that, I just wanted to do something a bit more difficult and challenging.

The first year I found really quite lonely and quite hard. It was awful. I was in this horrible hotel crying my eyes out for about two days.

I didn't want to get a job. I wanted to see all these places and all that obvious stuff, but mostly it was just to do something harder than I'd done before.
