Everything is difficult, and everything worthwhile is difficult. A certain need, a need not unlike Mickey had: to know, to understand, and I had that need to understand and to know.
With acting, I've always gotten by in life acting in situations. I'm a small person. I didn't have a chance to be a bully. But I could always act myself out of tough situations.
There are roles that are terrifying because they're large or you may feel that they're out of your line, but I'm never terrified once the actual work begins. Once you begin rehearsal, then it's small building blocks. It's solving little problems one at a time.
