Do you need to be strict with kids to make them shine in their career?

I don't know how much truth does it hold as I have seen examples from both worlds, as in kids shining in their career coming from a lenient as well as strict background. And also kids getting spoilt and turning out to be average in strict families. My grandmother was a very lenient woman and her kids grew up to settle in top brass in Indian administrative services. And my friend's mother was very strict and her siblings and her brothers did good in life but just cut above the average. I guess, being strict is no criterion for kids doing well in career, all you have to give a proper guidance at the right age. If you guide and show the right path to your kid, it will be more fruitful and worth it than creating a strict environment at home.
