In reference to parenting, the 4 quotes that resonates the most with me are:
It is easier to build a child than to repair an adult.
You only have 1 chance to raise a healthy child and it starts at birth.
A womb does not make you a mother. Bloodline does not make you family. If you see a spark in a child, pour into them, do not pass them by.
…and my absolute favorite, Your children are your message you send out to the world.
