studying is not about what’s worth it

This is one of my favourite scenes from My Neighbors the Yamadas.

Noboru: “Dad, do you think all this studying is really worth my time?”
Takashi: “Listen up! Studying is not about what’s worth it. Classes that seem worth it may turn out to be not worth it and therefore not worthwhile. But, sometimes things that are worthless may actually be worthwhile, worthless or not. So, it’s not about whether or not something is worthless or not!”
Matsuko: “What in the world are you talking about?”
Noboru: “That was so not worth it.”
