Sooooooooooo....
Let me get this straight. The hierarchy of ‘writer’s tasks’ in Hollyweird runs something like this:
Logline
Pitch
Beat sheet
Treatment
Outline
Scriptment
Screenplay
Cash the check ;-)
Curious.

Mike, you forgot to mention some other key items in the screenwriting life:

Canceled lunch meetings

Groveling with execs, producers, agents

Waiting for the phone to ring

Opening the trades to discover you've been replaced on your project

Chemical dependency

On the more serious side, if you haven't checked out the set of posts I put up called "How I Write A Script," you can go here to the 10th post and it has links to all the others. Everyone has their own approach, but that's more or less what a lot of working screenwriters do.
