I'm sorry, but what you are saying just does not match my personal experience, nor what the empirical studies suggest, which is the
exact opposite:
> When a child is praised more substantially for trying hard, you get things like staying up all night studying for a test. When you emphasize being smart and not needing to study, the child is more likely to push themselves such that they can land good grades without needing to study.
The way I've heard and personally experienced it, kids who get praised for being smart are more likely to procrastinate ("eh, I already get that anyway"), then try to cram everything in in the last minute.
> And the same thing applies to sports. If you emphasize effort, you might get a child practicing repeatedly something that they are already good at.
Similarly, studies suggest that by praising talent, you teach kids to stick to what they are good at immediately ("that's what I'm talented at"), instead of putting in the effort to learn stuff that they don't get immediately.
EDIT: Perhaps it depends on whether you praise below-average, average and smarter-than-average kids?
