You travel with the hope that something unexpected will happen. It has to do with enjoying being lost and figuring it out and the satisfaction. I always get a little disappointed when I know too well where I'm going, or when I've lived in a place so long that there's no chance I could possibly get lost.
The optimist underestimates how difficult it is to achieve real change, believing that anything is possible and it's possible now. Only by confronting head-on the reality that all progress is going to be obstructed by vested interests and corrupted by human venality can we create realistic programmes that actually have a chance of success.
Variety is very, very good. Going from medium to medium, if you get the chance to do it, from theater to television to film, which are all distinctly different, keeps me sharp. What works in one doesn't work in the other, and you have to be looking for the truth of the performance, whatever way that medium might demand.
