Most of the time for movies and stuff, with the exception of Jeff Nichols, who I've worked with a few times, you just don't know people too well. Everyone is cordial and nice and some people are very genuinely friendly, but once the movie is over you never see them again.
You cannot have that attitude of where I am going to tuck my tail between my legs and go home. You have to keep going back for more. That's why cycling is a very competitive sport. You have to have determination and drive to train hard and put forth a good effort.
