Acting is a great gig. It pays well, I get to meet some nice people, and it allows me to play a lot of golf. I'm a real lucky guy.
And as an actor - or even as a person in the industry - if you're unwilling to change, you're just going to get swamped. You've got to be flexible, and you've got to go with the flow. That's what I try to do as an actor.
I don't act because I love doing it, I act because it's my job. At the end of the year, I gotta pay my taxes, bills, doctors, insurance, car insurance, the occasional vacation. It's a wonderful job. The upside is that it is exciting and different... the downside is that it is an extremely insecure job.
