Email: Balance and variety [Sz]

I'm a big believer in balance between love and work in life. I agree that being adaptable is very important [and] variety should abound in a relationship (from interests to lovemaking to problemsolving). How shallow do you have to be to run out of topics to discuss? Ways to make love? Ways to compromise then kiss and make up? What is so hard about being an authentic and romantic human being? Does selfishness really have that great of a hold on humanity?
