"Parent Studies"...

There should be an official and mandatory "Parent Studies" class where kids get to learn from the mistakes their folks committed in their early years. They can then figure out how to avoid repeating those errors themselves. The kids can also learn the manifold characteristics that make their parents amazing and thus enhance their own positive traits. After all, parents are a child's first teachers. Besides, kids inherit some of the good as well as the bad from them anyway. A class like this conducted every day, even at home, will help parents mould their children into the best versions of themselves. The parents' own adult experiences will serve as the curriculum to nurture, guide, educate, and motivate their own flesh-and-blood. Add the contribution of grandparents and you have yourself a genuine legacy worth building.
