Topic: Childhood - a gauge of one's future (or something along these lines).
Main Idea: The influences gained and traits developed during one's childhood are deciding factors of one's personality growth and future.
Healthy influences include a nurturing environment for the development of body, mind and soul of a child, thorough character building lessons, positive examples in a child's immediate atmosphere and other facilities of this sort which can enhance a child's personality, character and help him grow up as a well-grounded adult, free of any inherited ethical or moral weaknesses.
