I don't think I'll be writing a poem on that. Namely because I don't believe it myself, however much of a reality it is from a certain point of view.
Personally, I believe that the meaning of our existence, our personal existence's, is to find what makes us happiest. Whether it be finding the one person to share your life with, raising a child or multiple children, becoming wealthy and/or successful, or being a psychopathic killer.
Whatever floats your boat, really.
Myself? I want to find that one person to spend the rest of my life with and have a family.
