What it contains is mostly thought as important by most essay readers, probably. How does he/she think? What does he/she mention about?
However, reading "Not So Deluxe Days" written by Matsuko Deluxe, a Japanese popular TV personality, tells us that we have to set great store by also the way how we show the contents, not just what it contains.
That's a compilation of the essays which Matsuko had written 2006 to 2014. So it tells us what he usually guess, what life he usually spends. Every chapter was by dictation, so you may think about the way he usually talks if you were familiar with him on television.
The contents tell that he is sensible. I have never seen him actually, but I am sure that what he mentions about is based on the view of a sensible moralist, as he himself talks in a chapter.
As mentioned above, I can almost agree with him but can't accept the manner how he shows what his thoughts.
Basically, Matsuko Deluxe belongs to the minority, which let him a TV personality. He can speak of commonsense because he is usually out of the majority. You can know what love is when you are out of love, for example. If you were in love, you cannot correctly get what the love is, how the love is formed.
Commonsense is usually prescribed by the majority which Matsuko Deluxe is out of. So he is considered easier to see what commonsense is.
That makes him so masochistic, the essays include a lot of his self‐torture.
Usually, we get tired of talking long with those who often show self‐torture. So reading his essays made me blue although the contents were very reasonable. However, his self-torture is surely a part of Matsuko Deluxe. We must accept. In other words, we have to take the blue for understanding what Matsuko Deluxe is.
