For my book series, Single Parent Wisdom, I asked over 50 single parents with children now grown to reflect on what worked and what didn't while raising their children. Compiling their answers and adding mine, I found 7 areas of advice recurring from their answers:

1. Be Consistent.
2. Be Patient & Loving.
3. Time is Short.
4. Be Age-Appropriate.
5. Reduce the Chaos.
6. Be a Role Model.
7. Live in the Present.
   

I list these at the beginning of each of the 16 books, starting with "25 Ways to Encourage Good Behavior."
