It is my belief that parents are the first and best teachers a child can have. Even if the parents aren't ready to be parents, the children will still learn whatever the parents are teaching. The children know only "that's the way its done and I can do that." You can guess that I think in order for parents to build excellent people they 1) prepare themselves for the never ending task of parenting, 2) they must work together put together the healthiest human they can and 3) then they must give that human the basic building blocks for excellence.
Public or private schools are primarily there to aid the parents through expertise and remediation to build the best possible human being.
You can predict then that if I were king I would insist that every person that had as a goal parenting they mus demonstrate that they have taken excellent care of themselves mentally, physically and spiritually in preparation for the huge task ahead of them.
We often can slow things down and choose our words with care, but there is almost nothing we can do with our actions. What we tend to forget is, "Do as I say and not as I do," merely points out the futility of hiding behind such things as "I never once told them that they could or should do that." When in fact, they already knew before we had the opportunity to use words they had seen how it is really done by the folk in charge.
This whole process deserves a great deal of time and attention. Few of us are apparently allowing for the time and we're too busy to focus on the problem.
