If I had a long-term partner, I dont think Id be an actor. Itd be too much of a strain; you have to work too hard to balance that life with a family and a mortgage and all that stuff - it would be too much.
I'm single because I move about so much that I can't really get attached.
I'm on my boat, training, rehearsing; I spend all my energy on the job that's coming up, and I found that's the way that works for me. The more energy you have on set, the better you'll be; it's all about being alive in that moment and listening.
