I would have been more charitable to the author if I read this a few years ago but of late, there's been so much negativity against any kind of pressure and a "glorification" of mediocrity and doing nothing done, it's almost like being an achiever is something to be ashamed of. Of course it has costs, of course there are risks. The point is to tackle and overcome all that and achieve something great. Not to sit idly being "safe" all the time.
There is a large spectrum between "high achievement" and "mediocrity". Opposing mediocrity (even worse "doing nothing done") to high achievement is a false dichotomy.
this is definitely a thing. I know people that when a child does something great whether it's academics or sports or something else it's hushed away like "what will the neighbors think?". I can't get my head around it.
Academic/professional is one and you can choose to opt out in which case you're not the target audience for this discussion which is fine.
