I agree and I have the evidence needed to back up your claims. Stable home life? checked. Parent-enforced discipline? checked. High parental expectations? checked. Through some involvement though, to some degree: we as parents always show real and positive interest on what our children are doing and learning without really interfering unless they explicitly ask for it, and I believe this helps dearly. I learned by doing, trying at first to get involved too much - proved to be a mistake which he corrected it by himself, jumping from an IT career to chemistry in notime and shortly hitting silver at international chemistry olympics. I never try to interfere anymore but just be there, always ready to talk about it and offer the emotional grounding they so much need. Kids will flourish. My elder is on his way to what seems to be a strong, well built medical career and my 6yr old oh boy, she's ready set.
