"Write until it’s a muscle you can flex on command."
This says so much, don't you think? And it is really good advice, and something I have been working on of late.
And you know what? I think it's working. This year, almost every day, no matter what, I have spent some time working on my current work in progress. It has required a lot of discipline and I have had to be creative and tenacious in making writing part of my daily routine, but as a result, my "writing muscle" is getting stronger and more obedient and I am so much closer to the whole "flex on command" thing.
Making writing a habit is well worth the effort, me thinks.
