知れば知るほど知らないことが見えて、深く知るほどさらに奥があると知る。
完全に知ることではなく、どこで満足し納得するのか区切りが必要。

The more you know, the more you realize what you don’t know; the deeper you delve, the more you understand there is still more beyond. It is not about knowing everything, but about knowing where to draw the line;where to be satisfied and content.
