#1. I would have taken school more serious and left sports out of the picture.
#2. Spent more time with my grandparents and gotten to know them and the legacy they were leaving behind.
#3. Not have been so driven in my first career that I overlooked my children as they grew up.
That is about all I would change. I have been blessed beyond belief with health and happiness. I do believe we create our own health by our habits and our happiness by the choices we make.
