It's often said that people with ADD can pay attention to things just fine if it's interesting to them. And that's kind of true, but only kind of. For example, people with ADD can pay attention if there's conflict involved, even if the situation is negative and uncomfortable. It's not that something has to be interesting, it has to be stimulating. And I would argue that if something's stimulating to someone with ADD, then it becomes something they like or are attracted to, because it relieves the uncomfortable feeling of the prefrontal cortex being "asleep."
