You’re still running out of time, but the culprit isn’t your motivation, it’s your schedule—how can you keep working on your thing if your work hours change every week? It happens to your humble chronicler, and has for years.
You’re going to have to schedule your creative time. Not at regular times, but around your job hours.
It’s best if you can get work in—and when I say “work” in this context it’s about the important stuff: art—before you head off to the job. Ideally the first thing you do when you get up in the morning. After the gym or morning exercise, if you do that, might be best, since I find I’m more lucid and motivated to get stuff happening then, rather than before when I’m still a bit groggy. Conversely, if you’re a poet, it might help the imagery to have the cobwebs of some dreaming hanging about. Try both.
An hour is great, two is better, but even 20 minutes a day is a couple hours a week, and it can pile up just like anything else. Get it on your calendar, shove your tantalizing social media and video services to the side for your work time. Tell yourself it’s just for a little while, you’ll get to it in just a bit.
This isn’t easy, but it can help establish a habit, and you can use the nagging itch to work on stuff to your advantage, because everything else in the world is conspiring—unwittingly—to distract, divert, and transfer your attention to literally everything else that seems easier and more fun. The world offers you endless ice cream. But your soul can’t survive on that, and in the long run, you get a lot more life out of the bread you bake yourself from scratch.
