Why plan a day
This line is one day. The plan is on top, and what happened is under it.
It is one turn of the Earth.
The Earth does not wait for a plan. Since you opened this page it has carried you hundreds of kilometres.
365 turns make one lap of the Sun.
A long life is about 80 laps. That is 29,200 days.
Today is one of them.
Left to itself, a day goes to whatever turns up.
By evening it is hard to say where it went.
So decide what the day is for before it starts.
Then do one thing at a time, and let a timer keep the record.
