Discipline.

I have been practicing the no-blame, cause-cause teachings of L. Ron Hubbard for many years. And I can say I've had great success with the technique in my marriages.

For instance, when Kate does something mildly silly -- like saying, "No I don't want to have a baby," or "I don't think six months in a sensory deprivation chamber will be good for me" -- I go along with it.

EVERYTHING WORKS OUT IN THE END.
