Mindfulness is supposed to be a practice, and it's not necessarily an easy thing you can do with all benefits and minimal work. It's also deeply personal and not a one-size-fits-all kind of thing.

I think schools should treat meditation like prayer, because it's essentially the same function, and we should just avoid it in the classroom.

Perhaps the real tragedy here is that many students will learn about mindfulness in schools and dismiss it as useless nonsense, when there actually may be something of value in there somewhere.
