I much prefer working with kids whose life could be completely upended by a reading of a book over a weekend. You give them a book to read - they go home and come back a changed person. And that is so much more interesting and exciting.
As a young actor people were trying to define who I was before I really knew that for myself. But I still remember thinking 'This is what I love doing and I hope I'm going to be able to do it forever.'
