Getting motivated, staying focused, keeping it what you want it to be, etc….

Of course you cannot edit a blank page.
Personally, for dialogue, roleplaying with myself, 2 characters and how they'd interact… thinking of it such a way can hekp in some scenes with staying on point.

I'm always reminded when I check my work of the scene in Futurama where a thousand light years away, a soap opera has just gone cancelled. Fry says "It took an hour to write so I thought it would take an hour to tape" or so.
