I meant to reply earlier because I did end up trying that weekend routine, and it worked better than I expected.
I started the morning a little slower, put my phone in another room, and gave myself one simple thing to finish before lunch.
That seemed to change the pace of the whole day.
I also took your suggestion about writing a tiny list instead of planning everything at once, which somehow made the chores feel lighter.
The weather helped too, so I spent a while outside and finally got around to tidying the patio and watering the plants.
By late afternoon I felt strangely reset, not rushed at all.
I am going to keep doing that because it was one of those small changes that made everything else feel easier.
If you want, next time I can send over the exact order I did things because the flow was probably the most helpful part.

I finally tested that idea you mentioned about keeping the evening simpler, and it made the whole week feel easier to handle.
I stopped trying to fit too many little plans into one night and focused on two things instead: making dinner without rushing and putting everything away before sitting down.
That small change left the room calmer and made the next morning less scattered.
I even remembered to set out what I needed before bed, which almost never happens unless I make a point of it.
It is funny how a modest routine can change my mood more than anything dramatic.
I think I forget that consistency usually helps me more than chasing a perfect day.
Anyway, thanks for nudging me to try something practical instead of overthinking it.
I am still adjusting it a bit, but for once it actually feels natural enough to repeat.
