We put way too much stock into working about the Days of the Week and the “core” hours that go along with it.
If I can, I make every day of the week different – sometimes I do a drop-off, other times I take my time, I might take a bus or drive, I go into different offices.
There are days I work like a madman from seven till noon and then stop for the afternoon and pick it up in the evening. Other days I got all day and do nothing at night.
I don’t miss any deadlines, my productivity is still topnotch.
Tuesday, Wednesday or Thursdays can be great days to take a day off if it’s better to work on Sunday because no one is around (family or otherwise).
But if you’re going to worry about two days of the week all the time, I guarantee you, you will start missing out on the other five.
