Have you ever imagined how life would be, had you known what you now know? Sometimes one wishes to time travel to their past, but with all the knowledge they now possess. The assumption is that they would make smarter choices and live a much better life.
Though we cannot time travel, we can try our best to teach our little children from the lessons life taught. Wishing to turn them into better human beings than we were. Tell them what they need to know about life and train them up in the way they should go (Proverbs 22:6).
The author put together these quotes/sayings when his own daughter could hardly comprehend what was going on around her. Even though the book was inspired by thoughts towards his daughter, it applies to both genders.
