My weekend is an important workday.
Moreover, on the weekend, I am busier than on weekdays.
I can say that I work better because I don't have to get emails, chats, and meetings.
So, the tiredness comes on every Monday -- it's a real downer.

However, I work on what I want to do first, among what I have to do.
So, I doubt if my productivity is increasing.
To begin with, no one seems to be able to define "productivity" itself.
-----
From the viewpoint of the nationality of Japanese,
"Works we feel enjoy are not productive"
"Works we feel pain are productive"
I sometimes think about the above.
Because I think that "my work I can feel enjoy" seems to be not counted as work.
