Some writers like routine. Some writers need routine. Some writers seem to have no problem just getting to it.
I juggle writing with life. With work. With chores and dating and obligations.
Steven Pressfield wrote a book, some time ago, called The War of Art. How to beat the resistance. I heard Seth Godin talking about it, and read it.
It’s inspiring, but, however many years later, I only know that the Resistance is a powerful thing.
If you can, give yourself every advantage against it. Otherwise, beating it back may not be possible when you’re trying to create something.
