Larry Niven Quote

For each human being there is an optimum ratio between change and stasis. Too little change, he grows bored. Too little stability, he panics and loses his ability to adapt. One who marries six times in ten years won't change jobs. One who moves often to serve his company will maintain a stable marriage. A woman chained to one home and family may redecorate frantically or take a lover or go to many costume parties.
