Unique ways to regain motivation to write?

What is a special way to get into the writing mood/mindset for you? Do you have something special you do, eat, drink, think, practice, whatever, to get that motivation back?

Since starting Uni I've had a really hard time finding the motivation to write fanfic when I have the time over. Sometimes I can, but most of the time I just don't get the ball moving. So I'm just looking for inspiration on how to handle that :)

I know the obvious one is probably just "sit down and write" but I'm looking for more specific or odd advice. Like maybe you sit down to write something really niche? Or you make tea, rewatch canon content, so on. Maybe you think it's something that only works for you, but I'd love to hear those too tbh
