Here we go again

Tomorrow we start our 8th year of homeschooling.  I'm so anxious!  It is a huge year for all 3 kids. Both boys are now in high school.  It is really hitting me the amount of things I want them to know and the short amount of time we have to cover ALL that.  I swear just yesterday they were in kindergarten and now we are talking about colleges, jobs and adulthood.  The enormity of that is overwhelming. At the same time I don't want to get so caught up in preparing them that we don't enjoy this time.  It definitely feels like a balancing act. I really can't believe we are going on 8 years. Can anyone believe we lasted this long?
