No matter all of your credits and accomplishments - you can be forgotten in a trice. The idea that you have to go back and start again after considerable success can destroy you if you're not strong. I never lost track of who I am and what I can do, because I continually find things to do, but not everyone has that resource.
After I finished school, I headed for Los Angeles, thinking, 'Movies. Beaches.' But I wanted to do serious stage work, so I upped sticks and moved to New York to study. I did the usual day jobs to support myself - waiting on tables, washing dishes, parking cars, anything to pay the rent. I was a terrible waiter, by the way.
