This is tricky. If I’m working full-time then yes, I do feel like I have to fit it in, but lately I have been working part-time while job searching and that’s been giving me more free time to write.
The biggest help I’ve found is to take advantage of scheduling features. If I’m working full-time, I will usually take the weekend to write a good three or four posts. That way I can schedule posts ahead of time and use whatever free time I have over the next few days editing and drafting up posts for later in the week.
Your schedule looks quite busy! Maybe reducing your posts to every other day would help. I find this improves the quality of my writing and frees up my time for other important things.
