Did anyone miss their calling to be a doctor?

Im too dumb and now too old to be a doctor not to mention too poor. But im also just not smart. But my heart loves when i get to research the human body anatomy and health stuff like that. I love finding out details about the human body like studying the skeleton and body organs etc. I feel sad when i study because it shows me i clearly missed a calling.
