Of course you must know who is the Prime Minister and President of your country. And basic understanding of what is why.
But after a certain level, too much knowledge hoarding is too much procrastination.
Is it wisdom to know where the world’s first elephant was found, who invented the world’s first bread or why do centipedes have the number of legs they do.
Even for my profession, I believe you need to be a proficient writer, which happens by consistency, understanding your audience, having empathy for them, and continuously improving upon your craft. Who invented the world’s first pen is a cute thing to know, but certainly not a necessary one.
Also, when the mind is free of facts it has been forcing into itself, it finally fathoms the fearlessness to fetch into its finest freedom.
