Homeschooling your child is a lot more than the value of academic progression, it is the time to impress the essence of the parent into your children.
Do not despise the day of small beginnings, small things things that you teach your children like table manners, praying every night, character building; these things are priceless.
When the children grow up, they will gain a strong confidence and security in their relationships, enabling them access to the values you taught them when they were growing up.
Proverbs 22:6 (NIV)
Start children off on the way they should go, and even when they are old they will not turn from it.
