In our case, finding a Lucy is unique. No one will ever find another Lucy. You can't order one from a biological supply house. It's a unique discovery, a unique specimen.
You will recognize your own path when you come upon it, because you will suddenly have all the energy and imagination you will ever need.
All I can tell you really is if you get to the point where someone is telling you that you are not great or not good enough, just follow your heart and don't let anybody crush your dream.
