alt Hacker NewsPeople naturally like learning some things and dislike learning others. The idea that if some learning is not interesting to everyone is misguided.
And no, something being useful and relevant does not make it interesting on itself. Even if you know it is useful you can just dislike having to learn it.
What is wrong with focusing on what you find interesting and doing only what is really necessary of what you do not? The problem is forcing everyone, regardless of talents or interests or aims, to follow the same curriculum
If you know its useful you are still motived. if you are motivated overall you will develop the discipline to get through what you do not find interesting and put the work in. it avoids situations like this from the first comment in this thread: "they would simply never study or do the homework I assigned them, and then they would do terrible on tests and I'd be stuck having to give them a bad grade."
