Finish what you start.

Even if you think it’s crap, you’ll be glad you finished it.

Do a lot of random favors for people so that when you make your movie you can guilt them into working on it for free.

Feeding your crew well is important.

Don’t underestimate the morale boost that a good lunch provides.

Entertain yourself.

That way, at least one person will like the film when it’s finished.
