I agree with you that learning to work hard is not a worthy goal on its own, but the praise effort vs ability debate isn't about encouraging a child to work hard but simply to praise them on what they have control over (their effort) vs their innate abilities. That makes a lot more sense, and is actually pretty close to what I was getting at (that what's often considered "natural intelligence" is really the end result of a whole lot of hard work aimed at the process of learning instead of the material being learned, and that it's not productive to pretend that one can't influence it).
