Too right, it's all about just getting used to it, and turning it into a habit. When I wake up in the mornings for the last 4 days, at around 7/8 o'clock, I put up a few listings, but what I might do when I get a chance is I'll have them set up and ready to go, and set them to publish at a certain time, which would be cool.
I'm doing something a little similar with photography. Selling stills and video to stock platforms like Shutterstock and Adobe Stock. A few sales so far, but yeah, gotta stick with it and realise it's a long game to play. The more you do it, the more chances of success.
Just make sure you fight the urge to get a bit lazy with it. I'm sure it'll lead to something with time.
It's all about having a routine, that's kind of how I keep motivation up, within the next two weeks, I'll have a good habit formed and then I'll keep at it.
That's amazing about the photo's, fairplay, it's great that there are so many ways now for people to earn from their crafts.
