I rarely spent more than five minute in there before I had kids. Now the "library" is a retreat. Turn on the exhaust fan, and it's like a white-noise sanctuary for as long as I can get away with it.I'm a quick worker in the, ahem, library and rarely spend more than 5 minutes there.
Beyond that, I can read the text transcript of most videos in about 1/3 the time it takes to watch a video. Why waste time when I can be learning three times as much in the same number of minutes?
