[Zachadoodle]

As a filmmaker and as someone who comes to work all the time, anything could happen. You don't know what may go on in another person's home. What may go on in their life. Even what news they may discover from a text message. Now, the issue isn't so much that you want to give up your job, but how can you deal with the stress of life creeping up on you when you are supposed to keep a positive upbeat attitude on a film set?

Same as every day of your life at any job, really. You put it on a shelf and concentrate on your work; you deal with it when you're at home.
