As a bright student who was never challenged in K-12, I can unequivocally state that this ultimately hurt me in the long run. I seriously didn't know how to study and didn't care to try learning when I actually needed it in some of my undergrad courses.
For example, when I took trigonometry in high school I did none of the homework, showed up to the tests and aced them. That led me to getting a C in that class (kindly the teacher advanced me to pre-calc, but forced me to retake trig as well). That's basically the attitude I had throughout high school and undergrad. I'm positive I could have amounted to more earlier in life (only years later did I return to academia to earn my PhD in CS after tiring of industry).
You can't forget the projects that are supposed to teach you that you're really gonna regret it if you don't have good study habits that you skate through fine without developing those habits. Causes all future teachers to lose credibility.
same-ish for me but times are different now. kids these days have all the knowledge in the world at their fingertips and it is really up to the kids (with a little guidance :) )
