Less precious.
If you are facing writer's block or resistance in one of its many forms, it may help to focus on making your today's work less precious. The best way to do that is to allow yourself to come back tomorrow and do more work, do better work.
When you know it's not your final blog, you can choose to publish what you have today. And the more you publish what you have today, the better you get tomorrow.
Perfectionism is nothing but procrastination in a smarter outfit.
