Determination is a start.  A good support group is always important.  I would study after i but the kids and hubby to bed.  I found it easier to study without the interruption.  If i had a big test to study for my husband would take the boys out for the day so i would have the house to myself.  I used a student organizer to keep track of the things i needed to do and when they were due.  As i finsihed them I would mark them off.  The support of my husband was the best motivator for me.
