If I can make a career for myself after Potter, and it goes well, and is varied and with longevity, then that puts to bed the 'child actors argument'.
There's no blueprint for where I should be. I see myself as a young, good actor who still has a lot to learn. There's nobody at any point in their career who is the finished article.
As far as I can tell, most actors' main motivation is self-doubt and neuroses.
I think, as an actor, and particularly if you are playing the lead in something, you have to view yourself as the head of department for the cast. All of the other departments are accountable and have somebody at the helm who is leading them all the time, and I don't think that the actors should be any different.
