I’d suggest that happiness for students might arise from challenge, from hard work fairly rewarded, or from the acquisition of new skills. But there is of course a quicker route: you keep students happy by not failing them. And then – surprise! – when they graduate they are not literate, or numerate, or knowledgeable enough to perform the work they have been studying for.
I’ve been forcing myself to read more long-form fiction. For the last couple of years I’ve noticed an impatience in myself when I’m reading, and instead of enjoying the text as it flows on the page, I feel like the author is not getting to the point quick enough. So, right now I’m trying to read more books, and slowing down.
