I'm saddened that my culture has formed me into a person whose first reaction to your comment was "wow, that's harsh" - because I mentally (and unwarrantedly) translated your comment into something like "if you have attention difficulties perhaps you should just accept that you are a low-value human who is hard class-locked out of many of life's joys and you should (quickly) figure out how to live in the way that least inconveniences your betters."
And my brain does this even though I'm gainfully employed and comfortable and happy (happy modulo general anxiety re climate, politics, war, and future generations)
My second reaction to your comment was more like "bingo, but it sure would be nice to have more clear directions about where one's actual place is." And it sure seems like there might be more such places and they'd be easier to find in a culture whose incentives were slightly (or significantly) different than those of mine (USA).
1. pay attention for the first 5-10 minutes. I'm really going to try this time!
2. hear something interesting, and your mind starts wandering
3. uhoh, i have no idea what the lecture is talking about now. i'll just keep daydreaming. don't even think about raisigin your hand to ask a question because it'll reveal that you haven't been listening.
4. go home and read the textbook to figure learn the content
