We raised 3 children and each one had to be dealt with differently. We laughed, we cried, we preached, we were their example and now that they are grown, I see that us being an example had a great impact on them as adults.
Our kids are loving parents, very patriotic, strong work ethics and try to be fair with their children when there is a need for discipline.
Taking time to enforce little things also has brought great rewards. Can't just check out when parenting but also good to chose your battles.
