You might have the blogging system down, posting twice a week or shoot, thrice a week sometimes.
You might feel like you're drowning.
Here's a quick hint.
If you think of something, do a draft. Then leave it.
When you think of something else, write another draft. Even upload a picture.
Pretty soon you have five, maybe eight draft posts. They'll take a bit more love before publishing but it won't be overwhelming.
Bit by bit, you'll have the rest of your twenty six posts. Better yet, you'll be in the habit of writing. You (and your brain) will be trained to write a few times a week, maybe even daily.
You can do this.
