Create “events” on your calendar
I've recently started using my Google calendar as an editorial calendar. All of my videos and blog posts are scheduled there ahead of time, so I can see what I need to be doing during the week. I also schedule time (an hour here or there) to work on the blog, and that is set up like any other appointment or obligation.
Always keep a running to do list
This kind of goes back to the Google Docs idea. Create a list of blog post topics, layout changes, or tweets to share. Whenever you need inspiration or have time to knock out some things, take a look at that list. You'll be surprised how many small gems you'll find there over time!
Revisit some things until later down the road
Don't force certain topics. Did you draw a blank or are running out of ideas? Give it time, let your brain focus on other things, then come back to it later down the road. I'm telling you, people will be able to notice when your posting just for the sake of getting content up.
Don’t compare yourself
There really isn't a win for doing this. It gets you nowhere. Trust me, I have spent years wondering "why didn't I get that opportunity" or "How does she have so many followers?". What a gigantic waste of time.
Wouldn't it be great to know that you have posts set up for every Monday of the next month? It can happen! Spend a span of work time scheduling a particular series. Once you've written all the copy, schedule the posts for the appropriate times.
