I have also taken quotes from some thought provoking authors and I ask you to consider them. If there are a few that challenge you, please accept the challenge. Entertain them with an open mind rather than just accept or reject them. Do not consider these to be true and do not use these, until you have tried them out for you.
The way to happiness is most commonly found when we treat others really well, love them, cherish them and serve them. If you want to be happy try doing that. That in itself would transform marriage, if both partners would accept that challenge. We are happy when we do for others and when we seek our own pleasure or happiness, we tend to make ourselves miserable. Every major religion has stories to teach that concept. When people used to initiate their young men, one of the first lessons was, “Your life is not about you.” If they did not get that lesson at that point, they sure did once children came along!
