The stuff I do is really simple:
Drink tea or coffee (because they're stimulants, so this is 100% a chemical kick. Though I can only really rely on that for a few days before it stops having the intended effect.)
Drink a Coke. For a different reason: Coke means it's fun time. So I can casually sneak up on making something.
warm showers when I feel anxioius or numb (to 'reset'. So I can have up to 3 'days' in my day.)
Don't jump the gun. I need to feel like what I'm making isn't hollow so if I only have one idea, or a flat version of that idea, I'll wait until it becomes multi-dimensional. Or I'll wait until I get other ideas to clump together with it. I get super bummed when I just make stupid things (it's a particular kind of stupid.....) so for me it's better to sit on things to eliminate the chance of that rather than feel like a moron.
*And what I mean by rut here is that I used to get a lot more excited about ideas...and more often. Feeling like I'm not settled/stable at a place is fucking with that. Almost everything feels superficial.....and then what? So what? That's what.
