Blank blogging counts too
Don't feel like blogging today?
Do it anyway.
If we only do things when we feel like it, nothing much will be done. I'm not saying you should force yourself, but at least give it a go and see what happens.
If you don't know what to blog about, blog about that. Write about how much you don't feel like writing.
More often than not, the mental restraints fade away. And if they don't, no harm done. At least you gave it a try, that's worth a personal upvote.
Keep on blogging, even if it sometimes ends up blank.
