I meant to reply sooner, but the afternoon slipped by while I was tackling a dozen little chores at once.
I did end up trying that routine you suggested, and it actually helped more than I expected once I stopped overthinking it.
The first round felt awkward, though after ten minutes everything clicked and the rest went smoothly.
I think the real difference was just keeping the instructions simple and not adding extra steps because that always slows me down.
I also moved a few things around so the room felt less crowded, which made it easier to focus without feeling distracted.
By the time I finished, I felt a lot less scattered and way more settled than I had earlier in the day.
If you want, I can write out exactly what I did in order so you can compare it with your setup.

I asked around because I was curious whether anyone else had the same issue, and it turns out they did, just not in exactly the same way.
What helped was stepping back and doing one thing at a time instead of trying to fix everything in a single push.
I usually make things harder by assuming there has to be some perfect approach, but this one got easier the second I quit chasing that.
Now I have a tiny checklist that keeps me from forgetting the obvious parts, which sounds silly but honestly makes the whole thing smoother.
I also gave myself a decent break in the middle, and that probably mattered more than I expected because I came back with better energy.
If you're still deciding what to do, I'd say keep it simple, start small, and adjust after the first try rather than waiting until it feels ideal.
That's pretty much what finally worked for me.
