Nothing improves your writing, I think, as much as your keeping writing.
There is an advantage in having a routine and working with the same people when you can and in writing as a regular thing and filming as a regular thing. That routine pays off for you. You get a lot of productivity that way, rather than sitting around waiting for inspiration and waiting for the perfect thing to happen. I would be much less productive that way.
Write regularly, day in and day out, at whatever times of day you find that you write best. Don't wait till you feel that you are in the mood. Write, whether you are feeling inclined to write or not.
I started writing every day. I never stopped.
Best thing is to get the words down every day. And it is time to start now.
Write something every single day, even if it's just three lines. And it doesn't matter if it's any good - just write something every day.
For me, the process always has to be pretty intense. I could never write just two or three days a week. It had to be every day.
Write a little bit every day, each day. Visit it, every day - in other words, show up for work.
If you show up to work five days in a row, nobody's going to pat you on the back - everyone does that. Well, do that with your writing. Just show up. Be there for it. When you get an idea, write it down somewhere and then be a steward of that idea.
I work just as much as I always worked. And I can't explain the fact that there have been a series of books coming rather regularly out of me. I work most days and if you work most days and you get at least a page done a day, then at the end of the year you have 365. So the pages accumulate and then I publish the books.
Putting words on paper regularly is part of the necessary discipline of writing. A journal is a great way to do that.
I write every morning. From about a quarter to nine to a quarter to one. It might be nine to one, or 8:30 to 12:30.
