Parenting

I need comments from all who have raised or are raising their children in the Lord.
How can I read these Bible verses and not feel worried?
What if I am not doing what I should be?
I think I will be reading these every day for a while. I need them fresh in my head at all times.

Deuteronomy 6:4-9 (NKJV)
Hear, O Israel: The Lord our God, the Lord is one! You shall love the Lord your God with all your heart, with all your soul, and with all your strength. And these words which I command you today shall be in your heart. You shall teach them diligently to your children, and shall talk of them when you sit in your house, when you walk by the way, when you lie down, and when you rise up.

Proverbs 22:6 (NKJV)
Train up a child in the way he should go, and when he is old he will not depart from it.
