I looked over the plan this morning and I think the easiest approach is to keep it simple.
I would start with the checklist we already made, then trim anything that feels overly complicated or hard to finish in one sitting.
The part that helped me most was setting a small timer and only focusing on the next step instead of the entire project.
I also moved a few things around on my calendar so I could stop pretending I would magically have extra energy later in the week.
That change alone made everything feel lighter.
If you want, I can send the revised notes after lunch because they are already mostly organized, and I only need to clean up a couple of comments and make sure the wording is clearer.
I do think you are closer than it seems, and once the first piece is done the rest will probably come together faster.

I meant to reply sooner, but I kept getting pulled into little tasks that looked quick and somehow took the whole afternoon.
I finally sat down and reread your note, and I think your first instinct was the right one after all.
The second version feels more natural, and the tone is easier to follow without sounding too formal.
I would only adjust the opening section so it eases in a little more smoothly and gives the rest of the message space to breathe.
Everything else seems solid to me, especially the ending, because it lands clearly without repeating too much.
I can help polish it tonight if you still want another set of eyes on it.
Just send me the latest copy and I will go through it carefully, add comments where useful, and keep the edits light so it still sounds like you wrote it from the start.
