Be passionate.

Moviemaking should be something you do with a story you need to tell. Your passion is always what drives it.

On heeding advice.

Peter Hedges, who was one of our advisors in the Sundance Lab, said 'You've got to write this screenplay because you have to. Not because you want to be a screenwriter or a filmmaker. You have to enter a tunnel and not know where you'll end up when you come out.'

Set realistic deadlines.

Even though it worked out for us, I would say don't make any festival your deadline! It causes an incredible amount of strain. We were editing as we were shooting and days off were spent in the editing room.
