I think the most important thing is to, without belligerence, stand up for what want. Argue compellingly if someone tries to change your script. Yeah, legally they can if they want to. But rather than give up, as some of the writers do, and just wail about how your script got rewritten, it's much more difficult - but well within the realm of possibility - to argue very sincerely, calmly, and reasonably from your point of view, such that the director or the producer might decide, "All right, let's do it that way."

For years I was doing the excruciating weightlifting of writing scripts - but then I stayed thin and someone else got all the muscles.

You have to be in California in order to write or direct movies. People say, "Oh, I'm gonna do it from Pittsburgh. I'm just gonna deliver scripts or fly out, like, once, then fly back." You have to make a full commitment. You have to actually get on a plane, come to L.A., rent a place, and live there. And that's how you forge your career. Not just sort of haphazardly. Once you've got a few hits under your belt, assuming you do, then go back and move away and correspond with the studio.

I've turned down lots and lots of work. Things that could have made me some money.

I wanted at one point to act, which is a weird thing for men to want to do. It's a very vain profession.

Every director should take an acting class. At least one. You know, you panic with actors. It's like, "Okay, this is back in college, I know how to talk to these guys. I know their vocabulary, and I get what they're saying back to me." So basically to learn the vernacular of acting, that's very important.

What I've learned being a writer is to just basically not buckle - not be belligerent, not be angry, not throw fits. Though there are times where you have to stand up and yell. If I've got to throw a chair, I'll throw a chair. There was a meekness about me when I started, and I think the meekness has sort of evaporated. I hope that it's left behind a more passionate person, not a meaner person. So I guess that's what I've learned.
