Some people are suspicious of others who have more than one talent. I've had poets tell me to my face that an actress can't be a poet.
I do less waiting by the phone than anyone I know in the business. I don't wait for a job. I just go on to my own work.
The fact is, as actors, everything we do, bad or good, is a contribution. To me, it is a positive thing to give people as wide a range of human behavior with some sense of understanding of that behavior or some clue to it.
