As you joked, we could simply space the cargo, forget the mission, and begin living our own lives. That would disturb me, and I know it would disturb you as well. One might go so far as to consider it an act of genocide. No, the mission and the potentials are factors of our existence we can't easily turn our backs on. Perhaps destiny is neither chosen nor thrust upon us, but woven throughout every aspect of our being.
Destiny is simply that which is to be experienced.
I see you have already decided you are spending the rest of your existence as a philosopher. Obviously, you are not spending yours as a comedian. Whatever the stuff of destiny, I hope I spend it with you. I love you, you hopeless romantic star chasing handsome starship, you. Love you back, Mother of our potential children.
