As a guy who runs a blog about the nuts and bolts of screenwriting, I sometimes get frustrated by aspirants who only want to dip their toes in, or believe they should be able to have a thriving film career in Duluth. The don’t want to commit fully to the form or the craft.

It is like I showed a chain saw to a early American colonist, and he said, “Can I cut down the tree without starting the engine? I don’t like the noise. Maybe I can just bang it against the tree?”
UPDATE: More discussion here.
