I do think opportunity breeds bravery. It's such a competitive profession, no one owes you anything, talent in itself is not enough. I went to drama school with so many great actors who are not doing it anymore and it's circumstantial.
I was sometimes called 'coconut' when I was at school.
I know I had my equivalents in Adrian Lester and Lenny James when I was at drama school. I remember David Harewood doing 'Othello' at the National, and Adrian Lester having done Cheek by Jowl's famous 'As You Like It and Company' at the Donmar. Not necessarily performances I saw, but just the fact they happened was massively encouraging.
