Given you had unlimited resources (including money) & if you had an abundance of free time how would you raise a child to give it the best chance as success & fulfilment in life.
What gender & why? Would you do anything to prepare like research any topics? Would adjust your diet/ health before you conceive to yield better genetics? What would be your preferred age of parenthood?
It’s also worth noting that we should live our life as well. Raising children is only one part of this life. Success and fulfillment depends on so many factors, that no effort can bring warranty, especially if we venture outside of social norms and expectations (do a monastic life brings success and fulfillment? How can a preparation for corporate life can help succeed in a monastic life?)
