Funny. But; being bored and being boring are two separate issues.
Prove it.
Nothing to prove.
Well, you said in your opinion they are two different things, I said support your opinion. If you don't want to, then don't. I guess this is why you, and your author, have a deep misunderstanding of this issue.
It is also why free thinkers like Gipper and I find this whole topic. . . well. . . sort of silly.
Because they ARE the same thing. SHEEP ARE BORING. And? They get bored easily.
Folks that go clubbing, go to bars, pay their taxes, vote for one of the two parties, do the nine to five thing, wash their shiny cars, watch their sports, go shopping, etc., do what everyone else does, and believe the narrative of the establishment, if someone isn't there to hold their hand, and tell them how to think and live their lives? YEAH, THEY GET BORED. They are boring.
This article is kind of weird, it is the author's misguided attempt at convincing himself at explaining why he is so dull, and perhaps a search for meaning? I suppose we might blame the Camus?

Existential materialists are generally sad people, but it is not their fault, they willingly become "human resources."
He reads a lot, that is clear, but he has no thoughts or ideas of his own. He is an expert at doing and saying what society says, and creating misguided and meaningless synthesis, but he lacks any spirit of his own. He lacks creativity. It is kind of sad. There is absolutely no insight here.
The folks he quotes in your article certainly don't have this problem.
I seriously doubt either Bertrand Russell or Arthur Schopenhauer have ever experienced true boredom. I am sure that their minds were always active.
This is why he completely does not get that there IS NO SUCH THING AS "BOREDOM," when you have a free mind. When your mind is free, you welcome "boredom," as it were, because that is just freedom.
In part, he starts to get it at the end of the article, that if you are bored, you are "boring."
Did you READ the article you posted?
". . . So instead of fighting boredom, go along with it, entertain it, make something out of it. In short, be yourself less boring. Schopenhauer said that boredom is but the reverse side of fascination, since both depend on being outside rather than inside a situation, and one leads to the other.. . "
Zen masters are never, ever "bored." They, like their minds, are free.
