(Part 2) Dr. Tim Kimmell, "Raising Kids for True Greatness". “If you aim your children at anything less than greatness, you’ll set them up to miss the whole point of their lives,” says author Tim Kimmel. In Raising Kids for True Greatness, Kimmel turns the definition of success on its head and guides you in preparing your child for a life that will easily eclipse the goals of those who are merely successful.
