Building a Life Well Worth Living As the Twig is Bent

Alexander Pope wrote, "As the twig is bent, so grows the tree." This books discusses bending the twig in the correct direction with a child on the verge of adulthood. So far as I know, there is no mandatory course taught in schools entitled "Build a Life Well Worth Living 101." Shouldn't there be be? As the twig is built early on in a child's life, so shall the child have a better chance of building a life well worth living.
