So why wake up early you ask? You are already exhausted from being a full time mom with a full time job (so actually you have two full time jobs), you are a college student cramming late at night, you are a newly married wife with all sorts of commitments, or you are someone who just LOVES their sleep. I can only tell you the benefits that I have received.
THE HOUSE IS QUIET
It is almost guaranteed that no one else is going to be up. Yes, there are mornings that one or both rugrats is up early but 95% of the time it is just me and my refrigerator humming.
