Accustom yourself not to be disregarding of what someone else has to say: as far as possible enter into the mind of the speaker.
Everybody's on their toes and focused on what we're about to do, and then there's this moment where you relax because you see that everybody is there to do the best that they can. Everyone opens up to one another right away. That's a terrific thing. I love that about actors. They know how personal this job is.
