Should you stop pursuing your goal if you stop enjoying it?

I was talking with a few friends about how they're not feeling passionate about school anymore, and I said something along these lines:<br><br>"Stop pursuing something if you stop finding it enjoyable. Nothing in life should be a chore, it's okay to take a break or do something else instead. No one should feel forced to do something if they don't enjoy it. Pursue the things that bring you happiness."<br><br>And they all looked at me, shocked, and basically told me that you can't stop pursuing school just because you don't enjoy it anymore, especially in high school. So I asked here, would you stop going after a goal if you stopped finding it enjoyable?
