I notice after myself that preparing a bunch of my daily posts beforehand is as detrimental as skipping writing for several days.
The key to daily blogging is having it as a habit. When I don’t skip a day, it feels like a small chore on my mental todo list. When I write several posts in advance, I let my brain relax on this habit.
It doesn’t matter how you skip a habit. If you skip it, it’s weakened.
