Summary
This quote humorously suggests that despite many people seeking advice on how to have a successful marriage, the true "secret" or key to achieving a truly happy and long-lasting relationship remains elusive. It highlights that every marriage is unique, and what may work for one couple may not work for another. Ultimately, it implies that there is no straightforward formula or surefire method for attaining marital happiness; rather, it requires understanding, compromise, and personal discovery within the context of each specific partnership.
