My attitude goes back to my childhood. I used to audition for theatrical roles, and you can't stand out in a room full of ambitious eight-year-old girls by acting the wallflower. I realised then that I couldn't do things half-heartedly.
When I was younger, I would go to auditions to have the opportunity to audition, which would mean another chance to get up there and try out my stuff, or try out what I learned and see how it worked with an audience, because where are you gonna get an audience?
My dad took me for an audition once, to show me, 'OK, you want to be a child actor, this is what it's like.' I sang a folk song about donkeys on this West End stage with this big director, and there was a queue of 200 girls all singing 'Memory.' I was terrible. Terrible.
For every successful actor or actress, there are countless numbers who don't make it. The name of the game is rejection. You go to an audition and you're told you're too tall or you're too Irish or your nose is not quite right. You're rejected for your education, you're rejected for this or that and it's really tough.
