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."

You can win more arguments then you might think as a writer, even though you legally have no recourse, and your script can get muddied and altered in any way possible. You can use reason, logic, and passion to argue persuasively for a case in your favor. So what I've learned is to just basically not buckle - not be belligerent, not be angry, not throw fits, but just not buckle.
Shane BlackI do think the challenge, in a way for me, is to write a narrative film and when you finish watching it you feel like it's a collage. You tell the narrative, you tell the story, but you feel like you've created this tapestry. But it also has a shape, a story. So I think there's a middle ground that I try to strike... away from where everyone else seems ready to go, which is, setup, payoff. You know, He's afraid of water, oh, and at the end he's swimming in water - oh, my God. I hate that stuff.
Shane BlackThe spotlight was on me. I pretended it wasn't, but it was, and for every wrong reason. It was all about money, it was all about my supposed competition with Joe Eszterhas over who'd be the highest-paid screenwriter. I didn't care. I just wanted to write stories, try to become a better writer, improve my style, change genres, even try new things. I didn't like action so much any more.
