I think for most people it’s just a matter of tradeoffs. You don’t have to be interested in the act of doing something in order to be interested in the consequence of doing that thing.

Someone who doesn’t like driving may still drive, and concentrate on driving the entire time, to get to a destination where they want to end up. For someone who doesn’t like to cook but wants to eat hot food, cooking is a means to that end.

Now, if you’re saying that you don’t think that tradeoff is worth it to you, maybe that’s true of them if they stop to think about it, too. But I’m not sure that’s what’s going on for most people who continue to work jobs they don’t like.
