The art world can be very intimidating because it's just so vast. You talk to people who are really clued in to all the young artists and coming into it you're never going to be able to catch up immediately, even though there's pressure to.

It's mainly about working hard and proving to people you're serious about it, and stretching yourself and learning. The mistake a lot of actors make, particularly young ones, is allowing themselves to feel that they're the finished articles, the bee's knees, and it's not true.

I definitely think that theatre is something I'll keep coming back to in my career for as long as I can. I also think theatre's something you have to be very fit to do. I am fairly fit, but I don't think I could do it all the time.

I know it wouldn't seem like I've had a lot of failure in my career, but there are things that I regard as failures, when I look at certain performances and go, 'That's not good enough.'
