I wish I would have known that teen boys need a hobby going into high school. Boys need to be out of the house and either working with their hands or have a purpose to fulfill. They need to work! (And video or computer games don’t count). They drive their mamas crazy being home all day. Also boys tend to pull away from their mamas and need their independence more than girls. That can create friction in relationships. They need their dads more at this time, but they do come back around and need mom after they mature a little. (smile)
But the best advice I was given was to “do everything heartily as unto the Lord and not to man.” I put my whole heart into my homeschool because of that.
