> I see this shit every day in other parents: “She hates to read!” “He’s lazy!” “She’s bad at math!” You are imprisoning your kid with your words, fuckers! That's spot on. It's really upsetting to hear people say that about children, especially people with authority (parents, grandparents). DON'T DO THAT! Or, if you have to do that (!?!) at least be positive. Don't tell a kid she's bad at math, tell her she's good at…
I would like to add that praising can backfire as well. For example, if a child gets a good grade and you praise its intelligence instead of their work it seems that they won't put in the effort next time.[1] 1: http://onlinelibrary.wiley.com/doi/10.1111/j.1467-8624.2007....
At the time all I would have wanted to hear is "it's okay if you don't do well on this one" (because it'd have taken the pressure off when I knew I couldn't do well) but what I really would have needed to hear would have been "yes, you're not well prepared, so you might not do well on this one but we'll help you prepare for next time so you won't be in this situation again".
I mostly got by avoiding homework and underperforming (I had the talent to do well enough but didn't put in the effort to take advantage of that) but my parents only intervened when I was at risk of having to repeat a year -- and at that point the only way to make progress was rote learning, which I hated and was (and still am) extremely bad at (because I had never done it before).
So IOW you may think your kid's a genius but the important thing is not to let them rest on their laurels. Don't obsess over grades but make sure your kid participates in class and does their homework like they should or else they'll skip on that out of habit and will be woefully underprepared when they run into situations where they can't get by on simply being a "genius" (which may be sooner than you think).
