1. Be extremely careful who you marry and have kids with. Be very careful before any marriage commitment is made to learn about addictive behavior, alcoholism, and substance abuse in the immediate family. Having kids with someone that has serious addiction themselves or in their immediate family (parents, grand parents, sisters and brothers) is a recipe for disaster. Ignore this at your own and your children's life long peril.
2. And have the backbone and self control to live below your means, stay out of consumer debt, and save at least 10-15% of every paycheck starting now not some [censored] day in the future.
