“Lasting happiness is the offspring of endurance.”

“Snatching happiness takes a lot more courage than enduring unhappiness.”

“Happiness is something that just happens because of the arrangement of circumstances, but joy endures in spite of circumstances.”

“The offspring cannot rely on its parents for disinterested guidance. One expects the offspring to be preprogrammed to resist some parental manipulation while being open to other forms. When the parent imposes an arbitrary system of reinforcement (punishment and reward) in order to manipulate the offspring to act against its own best interests, selection will favor offspring that resist such schedules of reinforcement.”

“Who of us is mature enough for offspring before the offspring themselves arrive? The value of [parenthood] is not that adults produce children but that children produce adults.”

“... Even an aardvarks think their offspring are beautiful”
