I am sure everyone wants the best for his/her family. Well then, the children from an early age must be disciplined. Characters must be trained to practice unselfishness, self-control and to make sacrifices for another member of the family.
If children are allowed to do what they want when they are young, they will want someone else's toy. But when they grow up, it will be someone else's wife/husband. Then they will cry out for divorce as soon as they do not get what they want.
It is important for married persons to try to improve their relationships as the years go by. Above all, the family that prays together stays together. The family rosary has kept families united, otherwise why does Our Lady give it so much importance every time she appears in different places?
