"I think the biggest obstacle is that the correct kind of work is completely unappealing to them."
Yes, sometimes (perhaps most of the time?) the most efficient way to improve is not the most intellectually satisfying. I think a clever thing to do is to try to make the efficient way also the intellectually satisfying way, but there will be limitations to that. It's like trying to be allowed to play a video game for a school project. Even if you succeed, the way you'll have to play the game for it to be largely educational will be so different that it might not have the fun you generally find in video games anymore. If you just play the game normally you might happen to learn a few things just by chance, but probably not that many things.
lots of nonsense going on. even math and computers nonsense involved. simply sad Polgars father was a loser and used his daughters as the only mean to achieve anything in life..............!!!
Although the usage must have felt good for the daughters, who are now famous and renowned.
