I think a certain amount of stress in life is good. The stress of just working, which takes effort - I think it keeps you going.
I never make conscious decisions.
Years ago I met Richard Burton in Port Talbot, my home town, and afterwards he passed in his car with his wife, and I thought, 'I want to get out and become like him'. Not because of Wales, because I love Wales, but because I was so limited as a child at school and so bereft and lonely, and I thought becoming an actor would do that.
I don't know why they gave me a knighthood - though it's very nice of them - but I only ever use the title in the U.S. The Americans insist on it and get offended if I don't.
