You can never fully put your finger on the reason why you're suddenly, inexplicably compelled to explore one life as opposed to another.
When I've gone back to work, it's always with that sense of inevitability. That may be a complete delusion, but it's the one that I need to get out of bed and go about my business. That sense that I can't avoid this thing. I better just get on with it.
I find it difficult to be in rooms now for long periods of time. I can usually take it for about an hour. Then I stride out.
When I did make the decision to focus on acting, I think my mother was just relieved for me that I had finally started to focus.
