Spend time with your spouse and kids. The most common argument for spending very little time with your family is that what little time you spend with them is quality time.
Quality time is an excuse used by people who put their career and job first, and the family second.
Be faithful to your spouse. Don't let yourself be attracted to coworkers or others that you meet. Set rules for the kids and expect them to obey. Kids who have no rules are not loved by their parents. Set rules and have consequences for breaking the rules.
