This is Kawaguchi Hidetoshi. This is a humble answer to the question.
Following Mr. Sato, it's a story from Naname, but...
One bad thing about Japanese people is that they think “do your best” = “be praised.” Therefore, no matter what, I try to do my best...
The problem is that “hard work” does not mean “good results.”
“Hard work” itself should not be the primary meaning, and it would be strange if the results (happiness) of hard work were not more important.
However, it doesn't mean “I won't work hard,” it means “I will do my best efficiently.”
To Agabushara, I realized that working hard anyway, the atmosphere as if it were a virtue is inherently strange, and even if I do my best, I want to do my best after firmly working out ways to do my best more efficiently and rationally.

Let's say it with a dodgy face. “I didn't work hard at anything when I was a student” (Mr. Masashi Kumagai)
