The best advice I’ve had is that when you are finishing for the day leave something to write about for the following day. Make a couple of notes on what comes next then leave it.

Hemmingway called it “Leaving water in the well”.

The next day when you sit down to write you have a guide as to what to do and you get right into it. I never get writers block when I’m on a roll. The thing that usually stops me in the middle of a writing day is TOO MANY ideas over-flowing. I have to stop and write down notes and chapter ideas… which of course innoculates me against writers block on other days.
