There are definitely roles within this industry that are industry-related, but to be a good actor, you really have to want to act first. At the same time, my goal was never to go to Hollywood to make movies. I think if you come here with that attitude, then you've missed a few steps.

ER' was so huge that whatever I did coming back to television, I'd have to feel as strongly about.

Flying back from New York, the flight attendant said 'God, I wished you were here yesterday, we had a stroke on the plane. I said, if I have a stroke on a plane, I hope the pretend doctor isn't the one on the plane. I want a real doctor.

I just spent a lot of time on 'ER' for that eight years. I also started working when I was 16, so by the time I left 'ER,' I was 40 years old, I had this incredible experience, my wife had this great company, we had four kids, it was like, 'Let's go to New York and live for a while and make that the priority.'

As I have told many, the only goal my dad had for me was to keep me alive to reach the age of reason! He had no aspirations for me vis-a-vis education, wealth, or anything else!

I used to be an awful asker. I was the 14-year-old who didn't correct the family I would babysit for when they gave me less money than we had agreed to, because it felt rude and scary.
