It’s hard to start, then it’s hard to stop.

Deborah Wright :

Remember, starting is always the worst bit.
Even now, after 4 years as a full-time writer, I procrastinate endlessly
before writing my first word of the day. There’s a weird inertia law
concerning writing. It’s hard to start, but once you do, it’s hard to stop.
You need to violently push through the blank wall in your brain that makes
you sit and stare gormlessly at the page. If you can’t think of what to
write in chapter one, then just plunge in mid-way and write chapter 7, or
the ending, or whatever springs to mind – anything just to break the ice!
