I do my best writing (and thinking) - and planning - in the evenings, heading into the night.
Mornings are for tweaking and revision.
I am the sort of person - who, if I have meetings in the morning - will plan my wardrobe (and set it out), the night before, put what I know that I will need into my briefcase, and set out stuff such as spectacles, wallet, keys, etc, where I have them readily to hand, all the night before.
Trying to do any - or all - of this in the morning kills me, and requires far too much mental bandwidth; yes, I can do it, but not without some serious suffering.
fairly Then, I just need to get up, shower, have coffee, (one is good, two are better) - plus, for preference, fresh prepared fruit juice, whereupon I am good - well, competent, or, rather, functional - to go.
