Fwiw, in my case what I used to think was boredom was actually an unrecognized anxiety disorder and associated anhedonia. I got a diagnosis but decided to treat it myself (mainly with meditation and sleep hygiene) and the concept of boredom has pretty much vanished from my life.
"Only <low status> people get <common condition that I do not have, or would like to signal I do not have>".
Once you see the pattern you'll see it everywhere.
For one, it's not about signaling superiority (which is what the pattern is all about) -- it's merely advice. The sayer (?) is not claiming they are exciting themselves, just that being bored is a sign of not recognizing opportunities to be engaged with something.
(Also, in the general case, the presence of the pattern or the snobbism of the one saying it, doesn't mean it's also wrong).
"My father used to say that only boring people get bored [...] I used to think it's only boring people who don't feel boredom, or cannot conceive of it in others."
I personally like the idea that only boring people can't conceive of boredom.
Stannis Baratheon to his daughter Shireen: "My father used to tell me that boredom indicates a lack of inner resources."
Shireen: "Were you bored a lot too?"

Ha, I was right! Wretched things.
Pretty annoying.
Because the programming of the lights is different to facilitate maximum throughput (f.e. with a green wave) in some periods, and the walk signs are on a constant/different timing then.
When I do that, I'm trying to tell the light what I need so it can figure out the correct timing signals to get me where I need to go faster.
