Often I'll try things that just won't happen the way I'd like them to, so hearing that they're not working saves me some wear and tear the next time around.
A message I've been telling myself: the cinema is very conservative, and unless you have a story that satisfies you, that is within the unchallenging zone, but you love it, you can't do it as cinema. Otherwise, you better go do it for television, which is more daring now.
I am one of those people who are blessed, or cursed, with a nature which has to interfere. If I see a thing that needs doing I do it.
