I circled back because I finally had time to test a few ideas and I think the easiest path is to keep things simple.
I tried doing everything at once yesterday and it just made the afternoon feel more scrambled than it needed to be.
If I were starting over, I would pick one task, finish it, take a short break, and then move to the next thing without overthinking the sequence.
I also noticed that I focus better when I leave my phone in another room for even half an hour.
It sounds obvious, but the difference is huge when interruptions stop stacking up.
Anyway, that is probably my best answer right now.
If you want, I can send a shorter version of the plan later with only the steps that mattered most, because I wrote down a few notes that turned out clearer than I expected.

I meant to answer earlier, but I wanted to wait until I had actually tried the routine for a few days.
Now that I have, I can say it feels easier when I prepare the night before instead of rushing in the morning.
I put everything in one place, make a quick list, and stop trying to remember every little detail in my head.
That alone keeps me calmer and a lot less distracted.
I am still adjusting a few parts, especially the timing, because I always assume things will take less time than they really do.
But overall it is going better than last week.
If you are dealing with the same problem, I would honestly suggest starting with the smallest change possible and repeating it until it feels automatic.
That approach usually works better for me than trying to overhaul everything at once.
