Lack of interest

He told me about how in high school, he was trying to tutor some other guy in Alegebra or something. It wasn't working very well. The guy couldn't keep his attention and effort focused on the subject.

The way he told it, the guy was trying - he wanted to learn, he wanted to focus, and he wanted to be interested.

But, he just wasn't interested, and there was nothing he could do about that.
