Here's a great little reflection piece of advice from I Take Joy:
"Do not fill your schedules with unnecessary activities and lists of textbooks and unnecessary busy work--it will wear you out and demotivate your children. Instead, delight in great stories, teach the word passionately. Greatly value and treasure words and ideas and history in front of your children so that they will fall in love with language and knowledge."
Children are already so motivated to greatness... this is easy for them and harder for us. My discipline and self-control--with regards to media, book choices, and time management--will bear exponential amounts of fruit in the girls. Motivation to keep going.
