I have played incredible knocks with the lightest of bats.
You can't invent Google, Facebook or the iPod unless you've mastered the basics, are willing to put in long hours and can pick yourself up from the floor when life knocks you down the first 10 times.
I think part of becoming a wonderful actor and part of defining your craft is defining yourself and being confident in yourself, so when the hard knocks come, and you don't get a job for five years, and your ego is being kicked around, you can pull yourself out of it.
If you want to be an actor, you should just get out there and do it. I don't go for the approach of first getting photos and an agent. I think you should start with the work, and the other stuff will follow. As with 'opportunity knocks,' you have to be ready.
Email knocks me off my game. It's just for the morning commute and end of the day. Some might think I'm slow to respond, but those who need to reach me know to send me a text during those hours.
As an amateur, I trained in some real hard schools of knocks. In Cuba, they would have judges on three sides of the ring just for sparring sessions. They train under exactly the same conditions as they fight, and it was a great experience.
